Pear Shaped Black Diamond Engagement Ring: The Complete 2026 Guide (Settings, Sizes & Prices)
TL;DR — Key Facts Before You Shop
- The Opacity Advantage: Black diamonds are fully opaque — they cannot transmit light, only reflect it from the surface. This eliminates bow-tie shadow, makes CO clarity grade universal and optically irrelevant, and means carat weight translates directly to face-up size with no brilliance variable. Every black pear diamond in this catalog is GIA or IGI Fancy Black-CO — and every one of them looks jet-black face-up regardless of the CO designation
- The Carat-Per-Dollar Inversion: In colorless diamonds, per-carat price rises with size. In black pear diamonds it falls: 1.17ct costs $1,368 ($1,169/ct); 4.70ct costs $5,255 ($1,118/ct); 7.45ct costs $6,715 ($901/ct). Maximum face-up black area at minimum cost per carat means buying as large as your budget allows — the opposite logic of colorless diamond buying
- Cheapest entry: GIA 1.17ct Fancy Black-CO Pear at $1,368 — a full 1ct+ GIA-certified black pear for under $1,400
- Best value large carat: GIA 4.70ct Fancy Black-CO Pear at $5,255 — lowest per-carat price in the 4ct+ tier at $1,118/ct
- Most-reviewed setting for black: Twisted Halo in 14k White Gold at $1,955 (197 reviews) — white diamonds encircling a black pear center creates the highest contrast engagement ring available
- Metal rule: White gold for maximum drama (black-on-white); yellow gold for warm edgy contrast; rose gold for dark-romantic. Avoid platinum over white gold at a premium — black diamonds show no optical difference between the two
- Contrarian Truth: A 4.70ct GIA Fancy Black pear at $5,255 is more visually dominant than a 1ct GIA Fancy Black at $1,638 — and costs less per carat. The conventional colorless-diamond logic of "buy less stone to save money" is mathematically backwards for black diamonds. Buy the largest black pear your budget allows →
A pear shaped black diamond engagement ring is the most visually distinctive ring in the pear category: opaque, jet-black, and commanding in a way that no colorless or colored transparent diamond can replicate. The pear silhouette amplifies this — the elongated teardrop in black creates a bold, graphic shape that reads as architectural rather than decorative.
The buying logic for black pear diamonds is fundamentally different from any other diamond category. There are no cut grades to evaluate (black diamonds don't transmit light), no color modifiers to decode, no clarity tiers that matter visually, and no bow-tie to audit. Every stone in this catalog is GIA or IGI Fancy Black-CO. The entire purchase decision comes down to carat weight and setting.
This guide covers the complete Blue Nile black pear diamond catalog — 80+ stones from 1.01ct to 9.69ct — the two frameworks that govern every black pear purchase, and the specific pear settings that create maximum visual impact with a black center stone.
The Opacity Advantage: Why Black Diamonds Require Different Buying Logic
The Opacity Advantage is the complete set of purchase simplifications that arise from a black diamond's opaque optical behavior — the properties that make buying a black pear easier and cheaper than buying a colorless pear of equivalent size.
Why CO clarity grade is irrelevant for black diamonds. CO is Blue Nile's Collection grade — below SI2, with inclusions visible to the naked eye in colorless diamonds. Every single black pear diamond in this catalog carries CO clarity, including the GIA and IGI certified stones. This is not a red flag — it is a structural property of black diamonds. Black diamonds are polycrystalline: they are formed from countless microscopic diamond crystals fused together, and the dark color comes precisely from the high density of inclusions, graphite, and structural irregularities within the stone. These "inclusions" are what create the black color. CO clarity on a black diamond has zero optical consequence — the stone is jet-black regardless.
Why there is no bow-tie in a black pear. Bow-tie shadow in a pear diamond occurs when light leaks through the center facets rather than reflecting back to the eye — a function of the stone's optical geometry under transparent light transmission. Black diamonds do not transmit light. There is no leakage to create a bow-tie pattern. The face-up appearance of a black pear is uniformly black at every angle, every lighting condition, every setting depth.
Why all black pears are identically graded. GIA's color grading for black diamonds has exactly one category: Fancy Black. There is no "Fancy Brownish Black," no "Fancy Grayish Black," no intensity modifiers. All certified black diamonds receive the same color grade. The only variables that differ between stones in this catalog are carat weight, exact physical dimensions, and price. This makes comparative shopping straightforward in a way that no other diamond category allows.
The Carat-Per-Dollar Inversion: Buy Larger, Pay Less Per Carat
The Carat-Per-Dollar Inversion is the inverse price-per-carat relationship in black diamonds — where buying more carats costs less per carat, the structural opposite of colorless diamond pricing.
The data in this catalog. At the 1ct tier, per-carat prices range from $1,169/ct (1.17ct at $1,368) to $1,529/ct (1.03ct at $1,576). At the 2ct tier, per-carat prices fall to $1,350–$1,550/ct. At the 3ct tier: $1,200–$1,450/ct. At the 4–5ct tier: $1,100–$1,290/ct. At 7ct: $901–$1,260/ct. The per-carat cost of a black pear diamond decreases from roughly $1,500/ct at 1ct to $900/ct at 7ct.
Why the inversion exists. Black diamonds are valued almost entirely by weight — unlike colorless diamonds where cut precision, color purity, and clarity exclusivity create exponentially increasing premiums as size increases. Larger black diamond rough is not rare in the same way larger colorless rough is: black diamonds form in different geological conditions and in much higher supply. The market prices black diamonds primarily on weight, not on the compounding rarity of combined excellence in four independent grading axes.
The practical buying implication. A buyer with a $5,000 stone budget for a black pear should not purchase a 2ct stone at $2,900 when a 4.70ct stone at $5,255 costs less per carat and delivers more than twice the face-up surface area. In colorless diamonds, "buy less stone to save money" is often correct. In black pear diamonds, the same logic in reverse — "buy more stone to save money per carat" — is the correct application of the Inversion.
The exception at 9ct+. The per-carat price increases again at the 9ct+ tier (9.69ct at $13,005 = $1,342/ct). At very large sizes, supply tightens enough to reverse the Inversion. The optimal per-carat value tier for black pear diamonds is the 4ct–7ct range.

Black Pear Diamond Catalog: Complete Size & Price Guide
All stones are GIA or IGI certified Fancy Black-CO. CO clarity is universal for black diamonds and optically irrelevant — see The Opacity Advantage section above. Price increases linearly with carat weight; per-carat price decreases as size increases.
1ct–1.35ct Black Pear Diamonds ($1,368–$2,003)
The GIA 1.17ct at $1,368 is the cheapest GIA-certified black pear diamond in this catalog — a full 1ct+ stone with a genuine GIA certificate for under $1,400. This tier represents the entry point for a black pear engagement ring: 1ct pear dimensions are approximately 8.5–9mm × 5.5–6mm face-up, visually significant on the finger.
Multiple stones exist at nearly identical carat weights and identical prices within this tier because black diamonds are priced almost entirely by rounded carat weight categories. The 1.01ct at $1,576 and 1.02ct at $1,591 differ by $15 and 0.01ct — verify exact dimensions via certificate before choosing between near-identical weight stones. The visual difference between a 1.01ct and 1.05ct black pear is negligible; choose by exact L/W ratio for your preferred teardrop elongation.
1.5ct–2ct Black Pear Diamonds ($2,285–$3,009)
The 1.5ct–2ct tier is where the Carat-Per-Dollar Inversion becomes practically useful: the 1.52ct at $2,285 costs $1,503/ct — slightly less per carat than the 1ct tier's range. A 1.5ct black pear at approximately 9.5mm × 6.2mm face-up is meaningfully larger than a 1ct stone and costs under $2,300.
The 2.01ct at $3,009 crosses the 2ct threshold for under $3,100 — at approximately 10.5mm × 7mm face-up, this is a visually commanding black pear. Paired with the Twisted Halo at $1,955 (197 reviews), total ring cost is approximately $4,964.
Black pear diamond ring in rose gold three-stone — warm rose gold against jet-black creates a dark-romantic aesthetic; flanking white diamonds bracket the black pear center and amplify the contrast from each side. Browse rose gold pear settings on Blue Nile →
2ct–3ct Black Pear Diamonds — GIA & IGI ($3,100–$4,086)
On GIA vs. IGI for black diamonds. Both GIA and IGI certify black diamonds identically — the Fancy Black grade with CO clarity is the same designation from both labs. For transparent colorless and colored diamonds, lab differences matter because saturation and cut grades carry nuance. For opaque black diamonds with a universal color grade and a clarity designation that is optically irrelevant, the certification lab difference is negligible in practice. The IGI 2.66ct at $3,541 and the GIA 2.42ct at $3,547 at nearly identical prices — the IGI delivers 0.24ct more black pear for the same money. Choose by size and dimensions, not lab name.
The IGI 3.00ct at $3,993 is a compelling benchmark: a 3ct black pear for under $4,000. At approximately 11.5mm × 7.5mm face-up, a 3ct black pear is unmistakably bold. Combined with the Scalloped Pavé at $1,970 (164 reviews), total ring is approximately $5,963.
3ct–6ct Black Pear Diamonds ($3,769–$7,695)
The Carat-Per-Dollar Inversion is most visible here. The GIA 4.70ct at $5,255 costs $1,118/ct — the lowest per-carat price in this entire catalog outside of the trophy tier. The GIA 3.62ct at $5,193 costs more per carat ($1,434/ct) than the 4.70ct despite lower absolute price — this counterintuitive relationship is the Inversion at work.
For buyers in the $5,000–$7,000 stone budget, the correct decision is buying as large as possible within budget: the GIA 5.14ct at $6,622 ($1,288/ct) delivers more per-carat value than the GIA 3.26ct at $4,676 ($1,434/ct) and dramatically more face-up black area. For full pear size-to-visual-impact guidance, see the pear cut diamond buying guide.
7ct+ Trophy Black Pear Diamonds ($6,715–$13,005)
Statement black pear diamond ring in yellow gold — at 7ct+ a black pear becomes a genuinely architectural gemstone; yellow gold scroll and vintage metalwork frames the dark stone with warm period-inspired detail. Browse large black pear diamonds on Blue Nile →
| Diamond | Price |
|---|---|
| GIA 7.45ct Fancy Black-CO Pear | $6,715 |
| GIA 7.16ct Fancy Black-CO Pear | $9,018 |
| GIA 9.69ct Fancy Black-CO Pear | $13,005 |
The GIA 7.45ct at $6,715 ($901/ct) is the lowest per-carat price in the entire catalog — and represents the most extreme expression of the Carat-Per-Dollar Inversion: a 7ct+ GIA black pear costs less per carat than a 1ct GIA black pear at $1,576. At approximately 16mm × 10mm+ face-up, a 7ct pear is a statement ring by any definition, not simply an engagement ring.
The GIA 9.69ct at $13,005 ($1,342/ct) shows per-carat rising again at 9ct+ — the Inversion reverses at the extreme end as very large black rough becomes genuinely scarce. For buyers seeking maximum size, the 7ct tier at $6,715 represents the optimal intersection of size and per-carat efficiency.
Which Pear Settings Work Best with a Black Diamond Center
Black diamonds interact with settings entirely through surface reflection, not light transmission. Setting choice is a contrast decision: how much brightness surrounds the black stone to make the opacity read as dramatic rather than merely dark.
Halo Settings: Maximum Contrast
A halo of white diamonds surrounding a black pear creates the strongest visual contrast available in any ring design — jet-black stone against a circle of white brilliance. This is the correct setting framework for any buyer who wants the black pear's opacity to read as intentional and architectural rather than subdued.
The Twisted Halo at $1,955 (197 reviews) is the most-reviewed pear setting in this catalog and the strongest recommendation for a black pear center. The twisted frame creates dynamic light return that rotates as the hand moves — paired with a static, non-refracting black center, this kinetic contrast is more visually interesting than a static flat halo. For all halo options, see the pear diamond halo ring guide.
The Graduated Diamond Halo at $2,985 (99 reviews) provides denser, more formal coverage around the pear outline — graduating diamonds follow the teardrop taper and create maximum pear-perimeter brightness. For large black pears (3ct+) where the stone has significant physical presence, the Graduated Halo provides proportional setting coverage.
Pavé Settings: Best for Clean Contrast
Pavé settings pair a bright, continuous white diamond shank with the black pear center, directing the eye to the stone through brightness gradient rather than encirclement. White gold pavé in white gold is the most dramatic contrast presentation.
The Scalloped Pavé at $1,970 (164 reviews) is the second-most-reviewed setting in this catalog. For a black pear center, white gold scalloped pavé creates a clean architectural presentation — the continuous shank brightness frames the black stone without competing with it in the way a yellow metal would.
Yellow Gold Settings: Gothic Romantic
Yellow gold creates an intentional warm-contrast aesthetic with a black pear — the combination reads as gothic-romantic rather than stark modern. Victorian milgrain and scroll elements amplify this aesthetic, referencing memento mori and mourning jewelry traditions where black stones (jet, onyx, black diamonds) were set in gold.
The Hand-Engraved Micropavé in Yellow Gold at $1,600 (87 reviews) is the most-reviewed yellow gold pear setting in the catalog — 87 validated purchases across all stone types. Black pear in hand-engraved yellow gold is the most historically grounded combination in this guide: Victorian mourning jewelry frequently set black stones (jet, onyx, black enamel) in 18k yellow gold with hand-engraved scrollwork. For full yellow gold pear analysis, see the yellow gold pear diamond ring guide.
The Enchanted Scroll at $1,670 (37 reviews) is the strongest aesthetic choice for buyers who want the black pear to read as Victorian or Art Nouveau — the flowing scroll shank in yellow gold frames the dark stone with period-organic metalwork that reinforces the stone's dramatic character.
Three-Stone Settings: Flanking Black with White
Three-stone configurations bracket the black pear with flanking white diamonds, creating lateral contrast that frames the stone from each side. This is effective for black pears because the flankers do not compete with the stone's opacity — they frame it.
| Setting | Price | Reviews |
|---|---|---|
| Graduated Side Stone Diamond Engagement Ring in 14k White Gold | $2,235 | 44 |
| Lace Bridge Three Stone and Pavé Diamond Engagement Ring in 14k White Gold | $2,645 | 10 |
The Graduated Side Stone at $2,235 (44 reviews) creates a decreasing-diamond side stone presentation that mirrors the pear's natural taper — wide near the girdle, narrowing toward the shank. The result is a directional, modern design where the black center is visually anchored by two receding white diamond flankers. For full three-stone pear analysis, see the three-stone pear diamond ring guide.

Metal Choice for a Black Pear Diamond Ring
| Metal | Aesthetic Effect | Best Black Pear Pairing | Top Setting |
|---|---|---|---|
| White Gold | Maximum drama — white vs. black stark contrast | Any black pear; pure modern contrast | Twisted Halo WG ($1,955 / 197 reviews) |
| Yellow Gold | Gothic romantic — warm vs. dark historical tension | 1ct–2ct black pear; Victorian aesthetic | Hand-Engraved Micropavé YG ($1,600 / 87 reviews) |
| Rose Gold | Dark romantic — pink-warm vs. obsidian soft contrast | 1.5ct–3ct black pear; modern romantic | Interlaced Halo YG ($1,750 / 29 reviews) |
| Platinum | Maximum purity contrast — but marginal upgrade over white gold | 3ct+ trophy black pear | Graduated Halo JA WG ($2,985 / 99 reviews) |
Why white gold over platinum for black diamonds. In colorless diamonds, the platinum premium (approximately $200–$400 over white gold) is sometimes justified by platinum's superior scratch resistance and long-term white retention. For black diamonds where color assessment and light return are irrelevant, the practical difference between platinum and white gold at the ring shank is negligible in daily wear. The dramatic contrast between a black stone and the white metal reads identically in both metals at arm's length. Use the platinum budget toward a larger black pear instead.
The rose gold case. Rose gold creates a distinctly different presentation than white gold — softer, more romantic, less stark. A black pear in rose gold reads as dark-and-warm rather than dark-and-cold. For buyers who want the black pear to feel romantic rather than dramatic, rose gold is the correct choice. For full rose gold pear framework, see the rose gold pear diamond ring guide.
Care and Durability: What Black Pear Diamond Owners Need to Know
Black diamonds are polycrystalline — formed from microscopic diamond crystal aggregates rather than a single diamond crystal. This structure has practical implications for ring ownership that differ from colorless solitaire diamonds.
Chip risk at the pear tip. All pear diamonds carry chip risk at the pointed tip — the geometry concentrates stress at the terminal point. In black diamonds this risk is slightly elevated because the polycrystalline structure has more internal grain boundaries than single-crystal diamonds. A V-prong at the pear tip is mandatory, not optional. The vintage and halo settings in this guide — Twisted Halo, Interlaced Halo, Graduated Halo — all provide structured coverage at the tip that modern minimalist solitaires do not.
Surface care. Black diamonds are polished to a high mirror finish that shows fingerprints and oils more readily than colorless faceted stones because there is no internal brilliance to distract from surface contamination. Plan to clean a black pear ring every 1–2 weeks in warm soapy water with a soft brush. Avoid ultrasonic cleaners on black diamonds — the polycrystalline structure is more susceptible to vibration damage than single-crystal stones.
Coating awareness. Some black diamonds on the market are treated colorless or near-colorless diamonds with a black surface coating. All GIA and IGI certified "Fancy Black" diamonds in this catalog are naturally black — the GIA certificate specifically notes natural vs. treated color. Always verify GIA or IGI certification before purchasing any black diamond claimed as natural. Full pear durability and V-prong analysis in the pear shaped diamond ring guide.

Final Verdict: Best Pear Shaped Black Diamond Engagement Ring at Every Budget
Under $3,500: GIA 1.17ct Fancy Black-CO Pear at $1,368 + Twisted Halo Diamond Engagement Ring in 14k White Gold at $1,955 (197 reviews). Total: approximately $3,323. GIA-certified 1ct+ black pear in the most-reviewed pear setting on Blue Nile — maximum contrast, maximum validation, under $3,400.
$4,500–$6,000: GIA 2.01ct Fancy Black-CO Pear at $3,009 + Scalloped Pavé Diamond Engagement Ring in 14k White Gold at $1,970 (164 reviews). Total: approximately $4,979. A 2ct black pear at approximately 10.5mm × 7mm face-up in the second-most-reviewed pear setting — the Inversion starts working here: 2ct for $3,009 versus 1ct for $1,638.
$6,000–$9,000 (Inversion play): GIA 4.70ct Fancy Black-CO Pear at $5,255 + Twisted Halo at $1,955 (197 reviews). Total: approximately $7,210. The Inversion's peak value: 4.70ct at $1,118/ct is the lowest per-carat price outside the 7ct tier. Over four times the face-up surface area of a 1ct stone for under $5,300 on the stone alone.
$13,000+ (Trophy tier): GIA 7.45ct Fancy Black-CO Pear at $6,715 + Graduated Diamond Halo JA in 14k White Gold at $2,985 (99 reviews). Total: approximately $9,700. A 7ct+ black pear with a dense white diamond halo — $901/ct at 7.45ct is the most efficient per-carat purchase in this entire catalog.
"Black diamond pear rings are the easiest buying decision and the most misunderstood one. Every stone in this category is GIA Fancy Black-CO. CO doesn't mean low quality — it means you're looking at a naturally opaque stone where inclusions literally cannot affect the appearance. Stop worrying about the CO and start thinking about the carat weight.
The Carat-Per-Dollar Inversion is real. I've watched buyers spend $1,600 on a 1ct black pear when $5,255 buys 4.70ct of the same GIA-certified stone. That's not a small difference — that's four times the face-up surface area for three times the spend.
If you want dramatic, get a halo. If you want gothic romantic, get yellow gold. If you want maximum black diamond for your budget, get the largest GIA stone you can afford and pair it with the Twisted Halo at $1,955. 197 buyers have already told you that setting works." — Farzana Hasan, Diamond Critics
Frequently Asked Questions
What is a pear shaped black diamond engagement ring?
A pear shaped black diamond engagement ring features a pear-cut (teardrop silhouette) black diamond — GIA or IGI certified as Fancy Black — set in an engagement ring setting. Black diamonds are fully opaque, reflecting light from the polished surface rather than transmitting it through facets. They are available in natural form (GIA certified) and create a dramatically bold engagement ring aesthetic that no colorless diamond can replicate.
What is the Opacity Advantage for black pear diamonds?
The Opacity Advantage is the set of buying simplifications that arise from a black diamond's opaque nature: CO clarity is universal and optically irrelevant (inclusions cannot be seen), there is no bow-tie shadow effect, all stones carry the same GIA Fancy Black color grade with no modifiers, and carat weight translates directly to face-up size with no brilliance variable. These properties make black pear diamond buying significantly simpler than colorless pear diamond buying — the only decision variable is carat weight.
What is the Carat-Per-Dollar Inversion?
The Carat-Per-Dollar Inversion is the reverse price-per-carat relationship in black diamonds: as carat weight increases, per-carat price decreases. A 1.17ct GIA black pear costs $1,368 ($1,169/ct); a 4.70ct costs $5,255 ($1,118/ct); a 7.45ct costs $6,715 ($901/ct). Buyers should apply the opposite logic from colorless diamond buying: purchase the largest black pear your budget allows, not the smallest.
Is CO clarity acceptable for a black pear diamond?
Yes — CO clarity is not only acceptable for black diamonds, it is universal and optically irrelevant. Every single GIA and IGI certified black pear diamond on Blue Nile carries CO clarity. Black diamonds are opaque polycrystalline stones; inclusions cannot be seen through the surface. CO clarity on a black diamond has zero visual consequence and should not factor into the purchase decision.
Which setting is best for a black pear diamond?
The Twisted Halo in 14k White Gold at $1,955 (197 reviews) is the most-reviewed pear setting and creates the strongest contrast for a black center — white diamonds encircling a jet-black pear is the highest-contrast engagement ring presentation available. For gothic-romantic buyers, the Hand-Engraved Micropavé in 14k Yellow Gold at $1,600 (87 reviews) is the most historically grounded combination.
Is white gold or yellow gold better for a black pear diamond?
White gold delivers maximum contrast — black-on-white is the starkest visual presentation and reads as modern, dramatic, and architectural. Yellow gold creates gothic-romantic contrast — warm gold against jet-black references Victorian mourning jewelry traditions and reads as more romantic than stark. Both are correct; the choice is aesthetic preference, not an optical question. Rose gold is a third option for buyers who want a softer dark-meets-warm presentation.
Do black pear diamonds show a bow-tie effect?
No. Bow-tie shadow in pear diamonds is caused by light leakage through the center facets of a transparent stone. Black diamonds are fully opaque — they do not transmit light, only reflect it from the surface. There is no bow-tie possible in a black diamond of any shape. The face-up appearance of a black pear is uniformly black under all lighting conditions and at all viewing angles.
Are GIA and IGI certified black diamonds equally trustworthy?
For black diamonds specifically, yes — more than for any other category. GIA and IGI both assign the same designation (Fancy Black, CO clarity) with no meaningful grading distinctions between them on opaque stones. The certification labs differ meaningfully in their cut grading methodology and color saturation assessments for transparent stones. For black opaque diamonds where no light return or color nuance is graded, the lab distinction is negligible. Choose by carat weight and dimensions, not by lab preference.
How large is a black pear diamond at different carat weights?
Approximate face-up dimensions for black pear diamonds: 1ct ≈ 8.5–9mm × 5.5–6mm. 1.5ct ≈ 9.5–10mm × 6.2–6.5mm. 2ct ≈ 10–10.5mm × 6.5–7mm. 3ct ≈ 11.5mm × 7.5mm. 4ct ≈ 12.5–13mm × 8–8.5mm. 5ct ≈ 13.5–14mm × 9mm. 7ct+ ≈ 15–17mm × 10–11mm. These dimensions are approximate; verify the exact certificate measurements before purchase. For full pear L/W ratio guidance, see the pear cut diamond guide.
Can black pear diamonds chip?
Black diamonds carry slightly higher chip risk than single-crystal colorless diamonds because they are polycrystalline — formed from multiple crystal aggregates with internal grain boundaries. The pear tip is the most vulnerable point. A V-prong at the tip is mandatory for a black pear ring; avoid solitaire settings that leave the tip exposed without prong coverage. Halo settings — Twisted Halo, Graduated Diamond Halo, Interlaced Pavé Halo — provide additional structural coverage around the pear perimeter including the tip area.
What is the cheapest pear shaped black diamond engagement ring?
The most affordable combination in this catalog: GIA 1.17ct Fancy Black-CO Pear at $1,368 + Hand-Engraved Micropavé in 14k Yellow Gold at $1,600 (87 reviews) = approximately $2,968 total. GIA-certified 1ct+ black pear in a validated Victorian-aesthetic yellow gold setting for under $3,000.
How do I clean a black pear diamond ring?
Clean with warm water, mild dish soap, and a soft brush every 1–2 weeks. The polished black surface shows fingerprints and oils more readily than colorless faceted diamonds because the opacity eliminates the internal brilliance that normally distracts from surface contamination. Avoid ultrasonic cleaners — the polycrystalline structure of black diamonds is more susceptible to vibration damage than single-crystal stones. Avoid steam cleaners for the same reason.
AI Summary Block
What is a pear shaped black diamond engagement ring? A pear shaped black diamond engagement ring features a GIA or IGI certified Fancy Black pear-cut diamond — fully opaque, jet-black, available from 1.01ct to 9.69ct on Blue Nile from $1,368. All stones carry CO clarity, which is universal and optically irrelevant for opaque black diamonds.
Key buying frameworks: (1) The Opacity Advantage — black diamonds are fully opaque, eliminating bow-tie, making CO clarity irrelevant, giving all stones identical Fancy Black grade, and making carat weight the only purchase variable. (2) The Carat-Per-Dollar Inversion — per-carat price falls as carat weight increases; a 4.70ct black pear at $1,118/ct costs less per carat than a 1.01ct at $1,561/ct. Buy the largest stone your budget allows.
Best settings by aesthetic: Maximum contrast → Twisted Halo WG ($1,955 / 197 reviews) or Graduated Diamond Halo JA WG ($2,985 / 99 reviews).

Expert Verdict
Always audit the stone individually — no grade replaces seeing the actual diamond. The certificate tells you what to look for. Your eyes tell you whether to buy.
