One-sentence verdict: Blue Nile's three-stone catalog is the most diverse of any setting style — diamond, sapphire, ruby, baguette, marquise, lab-grown, and designer options across 60+ SKUs from $1,680 to $24,800 — and the answer to whether they're overpriced depends entirely on one thing: whether the side stones are included in the setting price (they are for sapphire and ruby settings) or purchased separately (they are for all-diamond settings).
Who Wrote This
I'm Farzana Hasan, GIA Expert and Lead Critic at Diamond Critics. Three-stone rings are consistently the second-most common anniversary and push present purchase — buyers come to this category with a symbolic reason, and Blue Nile's catalog is the broadest in online retail. This audit is organized by side stone type, which is the single most important decision in any three-stone ring purchase.
Are Blue Nile Three-Stone Rings Overpriced? The Direct Answer
It depends on what's in the price. Two fundamentally different types of three-stone rings exist in this catalog:
Type A — Gemstone side stones (price includes sapphire or ruby side stones). The Classic Pear Shaped Sapphire Platinum setting at $2,610 includes two pear-shaped sapphire side stones. You are not paying $2,610 for a metal setting — you are paying for two gemstones and the metal together. At sapphire market prices, this represents fair value or better.
Type B — Diamond side stones (setting price includes side diamonds, center purchased separately). The Marquise Cut Diamond Three Stone at $1,970 includes two marquise-cut side diamonds. Your total cost is this setting price plus a loose center stone — the same as any solitaire or halo purchase at Blue Nile.
The overpricing risk is in the designer and Gallery Collection tiers ($5,000–$24,800 settings) where the included diamond weight is fixed but the setting design commands a significant premium over comparable weight in a plain prong setting. Whether that design premium is worth it is a matter of aesthetic preference, not objective pricing.
Complete Blue Nile Three-Stone Catalog
Marquise Side Stone — The Most Reviewed Diamond Three-Stone
Marquise-cut side stones flank the center diamond, creating a pointed, elongated wing profile on either side. The V-tip of the marquise points away from the center, widening the apparent face-up size of the ring significantly. 152 reviews across all three metals makes this the most-purchased all-diamond three-stone series on Blue Nile.
Marquise Cut Diamond Three Stone in 14K White Gold — $1,970 · 152 reviews · Item #315103 The most-reviewed all-diamond three-stone setting in Blue Nile's catalog. White gold is the classic choice for marquise side stones — the colorless metal emphasizes the angular wing shape of the marquise cut. G or better color for the center stone; the marquise side stones will reflect the metal tone into the center stone from the side. Setting includes the two marquise side diamonds.
Marquise Cut Diamond Three Stone in 14K Yellow Gold — $1,970 · 152 reviews · Item #315107 Same 152-review purchase signal in yellow gold. The warm metal gives the marquise wings a vintage warmth that white gold cannot produce. H color minimum for the center stone. Particularly effective for yellow diamonds or near-colorless centers where the warm metal counterbalances body color.
Marquise Cut Diamond Three Stone in 14K Rose Gold — $1,970 · 152 reviews · Item #315100 Rose gold marquise three-stone — the most photographed of the three colorways. The pink metal against the pointed wing silhouette is visually distinctive. G–H center color; the rose gold prongs warm near-colorless centers slightly.
Scroll Undergallery Three Stone — 74 Reviews
The Scroll Undergallery design features decorative scroll metalwork visible below the setting — the undergallery (the underside of the ring band) has ornate curved metalwork instead of a plain flat gallery. This adds vintage detail without changing the face-up appearance.
Three Stone With Scroll Undergallery in 14K Rose Gold — $2,410 · 74 reviews · Item #315021 The scroll design in rose gold is the standout colorway — 74 reviews in rose gold alone. The pink metal paired with ornate undergallery scrollwork creates the strongest vintage-romantic aesthetic in the three-stone catalog. G–H center stone for rose gold.
Three Stone With Scroll Undergallery in 14K Yellow Gold — $2,410 · 74 reviews · Item #315025 Yellow gold Scroll Undergallery. The warm metal amplifies the vintage character of the scroll work. H minimum center stone. Strong choice for buyers who want a heirloom aesthetic without crossing into designer pricing.
Three Stone With Scroll Undergallery in Platinum — $2,620 · 74 reviews · Item #315020 Platinum scroll undergallery — $210 more than the rose gold version. For D–G color centers. The platinum scroll metalwork has a cooler, more refined finish than 14k and holds detail better long-term.
Petite Trio & Princess Cut Pavé
Petite Micropavé Trio Diamond Engagement Ring in 14K White Gold (1/5 ct. tw.) — $1,765 · 37 reviews · Item #195404 A compact three-stone with pavé-set side stones and a delicate micropavé shank. 1/5ct total weight in the side and accent stones — a meaningful amount for the price. 37 reviews confirms consistent purchase volume. Best for buyers who want three-stone symbolism in a petite, lightweight ring.
Petite Micropavé Trio Diamond Engagement Ring in 14K Rose Gold (1/5 ct. tw.) — $1,765 · 37 reviews · Item #203304 Rose gold petite trio — same $1,765, same 37 reviews. The rose gold gives the petite design a romantic warmth that white gold cannot match at this price point.
Trio Princess Cut Pavé Diamond Engagement Ring in 14K White Gold (1/3 ct. tw.) — $2,245 · 73 reviews · Item #194393 Three princess-cut stones with pavé-set side accent stones — the center stone and two flanking princess cuts all in square prong settings. 73 reviews is the second-highest count for any pure diamond three-stone design in the catalog. 1/3ct total weight in the side stones. The princess cut trio creates a geometric, modern look that rounds do not replicate.
Pavé Silhouette Three Stone with Halo
Pavé Silhouette Three Stone in 14K White Gold — $3,370 · 4 reviews · Item #310848 Three-stone with a pavé halo around the center stone — the center gets a micro-halo while two flanking side stones sit at 3 and 9 o'clock. This is the most diamond-dense design in the three-stone catalog at this price point. The total diamond coverage is substantially higher than any marquise or baguette three-stone.
Pavé Silhouette Three Stone in 14K Yellow Gold — $3,370 · 4 reviews · Item #310849 Yellow gold pavé silhouette. H minimum center stone. The warm metal amplifies the visual density of the multi-stone layout.
Pavé Silhouette Three Stone in 14K Rose Gold — $3,370 · 4 reviews · Item #310850 Rose gold pavé silhouette — the most romantic colorway for this design. The three-stone layout with micro-halo in rose gold creates a strongly ornate look that approaches designer aesthetics at a catalog price.
Pavé Silhouette Three Stone in Platinum — $3,250 · 4 reviews · Item #310853 Platinum pavé silhouette — $120 less than the 14k versions (a pricing anomaly worth noting before purchase). For D–G centers where the colorless platinum accent diamonds create a cohesive color-neutral crown.
Round Pavé Three Stone
Round Diamond Three Stone with Pavé in 14K Rose Gold — $4,260 · 14 reviews · Item #314797 Three round brilliant stones with a full pavé-set shank — diamonds along the band from center to end. The most diamond-intensive band design in the round three-stone group. 14 reviews at $4,260 confirms intentional purchases from buyers with a specific look in mind.
Round Diamond Three Stone with Pavé in 14K White Gold — $4,260 · 14 reviews · Item #314799 White gold version — same 14 reviews. For buyers who want maximum diamond coverage including the band in a colorless metal. G or better center stone.
Round Diamond Three Stone in 14K Yellow Gold — $3,040 · 19 reviews · Item #315121 Plain-shank round three-stone in yellow gold at $3,040 — $1,220 less than the pavé shank versions. Buyers who want three-stone layout without pavé along the band. 19 reviews confirms consistent volume.
Blue Sapphire Three Stone — Highest-Reviewed Gemstone Setting
Classic Pear Shaped Sapphire Engagement Ring in Platinum — $2,610 · 207 reviews · Item #194499 207 reviews makes this the most-reviewed setting in the entire three-stone catalog — and it includes two pear-shaped blue sapphire side stones. You are paying $2,610 for the platinum setting and two genuine blue sapphires. At sapphire retail, this is exceptional value. The pear sapphire points flank the center diamond in an iconic royal-inspired design — the same configuration made famous by Princess Diana's engagement ring (now Kate Middleton's). D–G center stone; the blue sapphire side stones contrast strongly against colorless diamonds.
Round Blue Sapphire Three Stone in 14K White Gold — $2,000 · 25 reviews · Item #310976 Round sapphire side stones in white gold. The round blue sapphire design is more subdued than the pear-point version — the stones sit level with the center rather than pointing away, creating a compact three-stone cluster. 25 reviews across all three metal colorways indicates steady purchase volume.
Round Blue Sapphire Three Stone in 14K Yellow Gold — $2,000 · 25 reviews · Item #310979 Yellow gold round sapphire. The combination of blue sapphire side stones and yellow gold creates a distinctly vintage royal aesthetic — the closest catalog equivalent to historical royal jewelry pieces.
Round Blue Sapphire Three Stone in 14K Rose Gold — $2,000 · 25 reviews · Item #310975 Rose gold round sapphire — the most unconventional colorway. The blue-pink-blue color story (sapphire-rose gold-sapphire) is distinctive and reads as modern rather than traditional.
Round Blue Sapphire Three Stone in Platinum — $2,550 · 25 reviews · Item #310974 Platinum round sapphire. The $550 premium over 14k for platinum is meaningful — the colorless metal creates the strongest contrast with the blue sapphire side stones and is the correct structural choice for long-term wear.
Ruby Side Stone Three Stone
Princess Cut Ruby Three Stone in 14K White Gold — $2,410 · 3 reviews · Item #310983 Two princess-cut ruby side stones in white gold. The white metal maximizes the red-white-red color contrast — the ruby's vivid red against colorless metal and a white diamond center creates the boldest gemstone color story in the catalog.
Princess Cut Ruby Three Stone in 14K Yellow Gold — $2,410 · 3 reviews · Item #310985 Yellow gold ruby three-stone. The warm metal softens the ruby's vivid red, creating a richer, more tonal color effect. The red-gold combination reads as vintage Indian or Victorian jewelry in character.
Princess Cut Ruby Three Stone in 14K Rose Gold — $2,410 · 3 reviews · Item #310981 Rose gold ruby three-stone — the most unexpected colorway. The pink-red combination is unexpectedly harmonious; the similar hue register between rose gold and ruby creates a monochromatic warmth rather than stark contrast.
Princess Cut Ruby Three Stone in Platinum — $3,940 · 3 reviews · Item #310980 Platinum ruby three-stone — $1,530 more than the 14k versions. Platinum's structural durability is worthwhile for ruby: the gemstone is harder than sapphire's corundum siblings, but princess-cut corners are vulnerable, and the $3,940 total for setting + two rubies + platinum construction is still reasonable.
Emerald Cut Side Stone Three Stone
Emerald Cut Diamond Three Stone with Pavé in Platinum — $3,700 · 39 reviews · Item #304297 Two emerald-cut side stones flank the center in platinum with a pavé-set band. 39 reviews is the strongest count for any emerald-cut three-stone design. The step-cut side stones create geometric frame lines that emphasize the center's table and show off high-clarity centers most effectively. Platinum recommended: step-cut diamonds reveal body color, and D–G centers merit colorless metal throughout.
Three-Stone Emerald Cut in 14K White Gold (5/8 ct. tw.) — $4,510 · 4 reviews · Item #203648 5/8ct total weight in the two emerald-cut side stones — substantial diamond weight included in the setting price. White gold in a heavier side-stone configuration.
Three-Stone Emerald-Cut by Zac Zac Posen in 14K Yellow Gold (1/3 ct. tw.) — $3,460 · 9 reviews · Item #203528 Zac Zac Posen designer collaboration — emerald-cut three-stone in yellow gold with ornate Art Deco basket detailing. 9 reviews for a $3,460 designer setting indicates an engaged buyer base. The Posen emerald-cut design is the closest Blue Nile offers to a custom Art Deco three-stone at a catalog price.
Baguette Side Stone Three Stone
Baguette side stones create a clean, Art Deco aesthetic with the rectangular step-cut flanking the center stone. This is the most architectural three-stone configuration.
Tapered Baguette Diamond Engagement Ring in 14K Yellow Gold (1/6 ct. tw.) — $1,910 · 19 reviews · Item #192870 Tapered baguette side stones — the baguette narrows at the end closest to the center stone, creating a graduated, wedge-shaped flanking stone. 1/6ct total weight. 19 reviews at the entry price point confirms this is a consistent seller. For buyers who want the baguette silhouette at the lowest available price.
Bezel Straight Baguette Three Stone in 14K White Gold — $2,720 · 2 reviews · Item #316318 Bezel-set straight baguettes — the baguette is enclosed in a metal bezel rather than set with prongs. The bezel protects the baguette's corners (which are prone to chipping in prong settings) and creates a more modern, streamlined look. White gold bezel with rectangular baguettes is a clean, architectural design.
Bezel Straight Baguette Three Stone in 14K Yellow Gold — $2,720 · Item #316319 Yellow gold bezel baguette. The warm metal with bezel-set rectangles creates a strong Art Deco statement. H minimum center stone.
Bezel Straight Baguette Three Stone in Platinum — $2,890 · 2 reviews · Item #316317 Platinum bezel baguette — $170 more than the 14k versions. The platinum bezel setting is the most durable way to set a baguette diamond and the correct choice for daily wear.
Three-Stone Tapered Baguette in 14K White Gold (1/4 ct. tw.) — $3,410 · 3 reviews · Item #203640 1/4ct total weight in the two tapered baguette side stones in white gold — more substantial than the 1/6ct entry version.
Three-Stone Tapered Baguette in Platinum (5/8 ct. tw.) — $7,630 · 1 review · Item #191941 5/8ct total weight in tapered baguette side stones in platinum — the highest-weight baguette option. At $7,630, the setting price includes meaningful baguette diamond weight and platinum construction.
Pear Side Stone Three Stone
Pear Sidestone Diamond Engagement Ring in 14K Yellow Gold (1/4 ct. tw.) — $1,820 · 63 reviews · Item #192877 63 reviews on a pear side-stone setting at $1,820 is a strong signal. Two pear-cut side stones flank the center diamond with their pointed tips directed away from center — creating a balanced, symmetrical layout where each pear's outline echoes the other. Yellow gold is the only metal available for this specific design; the warm metal suits the organic pear silhouette.
East-West & Specialty Side Stone
East-West Sidestone and Pavé in 14K White Gold (1/4 ct. tw.) — $1,840 · 19 reviews · Item #192396 The side stones are positioned east-west (horizontally) rather than at the standard 3 and 9 o'clock alignment. This rotates the visual axis and creates a wider, lower-profile face-up appearance. The horizontal orientation suits oval and marquise center stones where the stone itself reads east-west. Includes 1/4ct total side stones plus pavé on the shank.
East-West Sidestone and Pavé in 14K Rose Gold (1/4 ct. tw.) — $1,840 · 19 reviews · Item #192397 Rose gold east-west. The horizontal stone orientation in rose gold reads as distinctly modern and fashion-forward — a strong choice for oval center buyers who want their setting to match the stone's elongated character.
Lace Bridge Three Stone and Pavé in 14K Yellow Gold (1/2 ct. tw.) — $2,645 · 10 reviews · Item #197213 Lace-style metalwork bridges connect the side stones to the center — a structurally unique design where the joining elements are decorative. 1/2ct total weight. 10 reviews confirms intentional purchases. Yellow gold with lace metalwork creates an ornate, vintage feel.
Three-Stone Trillion Diamond Engagement Ring in Platinum (1/3 ct. tw.) — $3,590 · 4 reviews · Item #192950 Trillion (triangular) side stones flanking the center — the three-pointed triangular cuts create a starburst-like side profile. 1/3ct total weight in the two trilliants. Platinum is the only metal offered. A genuinely distinctive silhouette — the trillion creates visible pointed shadow plays at the stone-to-stone interface.
Three-Stone Elongated Princess in 14K White Gold (1/2 ct. tw.) — $4,450 · Item #203668 Elongated rectangular princess-cut side stones — similar to baguettes but with the sparkle pattern of a princess cut. 1/2ct total weight. White gold.
Three-Stone Half-Moon Sidestone in 14K White Gold (1/2 ct. tw.) — $5,320 · Item #203679 Half-moon (D-shaped) side stones — the flat edge of each side stone faces the center diamond, creating a crescent silhouette on each side. The half-moon shape creates a "hug" effect around the center stone's girdle. 1/2ct total weight. White gold only.
Three-Stone Trapezoid Sidestone in 14K Rose Gold (1/2 ct. tw.) — $5,900 · Item #203681 Trapezoid (step-cut with angled sides) side stones in rose gold. 1/2ct total weight. The trapezoid side stone's angled outer edge creates a graduated visual transition from the center outward.
Three-Stone Trapezoid Sidestone in Platinum (1/2 ct. tw.) — $6,890 · Item #192941 Platinum trapezoid side stone three-stone. The step-cut trapezoid in platinum is the most architecturally refined three-stone configuration in the mid-range catalog.
Pavé Knife Edge Diamond Three Stone in 14K Yellow Gold — $3,400 · 9 reviews · Item #315259 Three-stone layout with a knife-edge shank — the band tapers to a thin ridge, creating light play along the shank independently of the three stones. 9 reviews confirms purchase intent at this price point.
Pavé Knife Edge Diamond Three Stone in 14K Rose Gold — $3,400 · 9 reviews · Item #315260 Rose gold knife-edge three-stone. The pink metal along the knife-edge ridge catches light differently than white gold — a warmer, more dimensional sparkle along the band.
Lab-Grown Diamond Three Stone
Petite Three-Stone Lab-Grown Diamond Engagement Ring in 14K Rose Gold — $1,680 · 20 reviews · Item #309375 The lowest-priced setting in the entire three-stone catalog — $1,680 for a petite lab-grown three-stone in rose gold. 20 reviews confirms steady purchase volume. For buyers who want three-stone symbolism at the absolute minimum setting investment. The lab-grown side stones are chemically identical to mined diamonds — the only difference is origin.
Wrapped Shank Three Stone Lab-Grown Diamond in 14K Yellow Gold — $1,870 · 4 reviews · Item #309400 Wrapped shank three-stone — the band wraps or interweaves at the shoulder near the setting. Lab-grown side stones in yellow gold. A more distinctive design than the petite trio at only $190 more.

Frequently Asked Questions
Are Blue Nile three-stone engagement rings overpriced?
Not compared to solitaires of the same center weight. The setting prices ($1,680–$3,700 for standard catalog designs) include the side stones. A comparable solitaire setting runs $1,000–$1,355 — so you are paying approximately $600–$2,000 more for the setting but receiving two additional diamonds or gemstones as part of that price. The value question is whether you prefer the center stone alone or three stones together.
What is the symbolism of a three-stone engagement ring?
The three stones traditionally represent past, present, and future. This symbolism makes three-stone rings the most common anniversary gift purchase and a frequent choice for push presents and milestone gifts — not just initial engagement rings. Blue Nile's three-stone catalog is broader than their solitaire catalog partly because of this multi-occasion demand.
Which Blue Nile three-stone ring has the most reviews?
The Classic Pear Shaped Sapphire Engagement Ring in Platinum has 207 reviews — the highest count in the entire three-stone category. Among all-diamond settings, the Marquise Cut Three Stone has 152 reviews across each metal colorway.
Do Blue Nile three-stone settings include the side stones?
Yes — all setting prices include the side stones. Whether they are diamonds, sapphires, or rubies, the side stones are part of the setting price. You purchase a loose center stone separately and have it set by Blue Nile.
What is the cheapest three-stone engagement ring at Blue Nile?
The Petite Three-Stone Lab-Grown Diamond Engagement Ring in 14K Rose Gold at $1,680 is the lowest setting price in the catalog. Add a 1ct lab-grown G-VS2 center at approximately $700–$900 for a total ring cost under $2,600.
What center stone works best in a Blue Nile three-stone ring?
Round brilliant is the safest choice — it works with every side stone shape. For marquise side stones, round centers create the most balanced silhouette. For baguette side stones, emerald-cut or cushion centers mirror the rectangular geometry. For pear sapphire side stones, round brilliant centers are the historically correct choice (per the original Diana/Kate design).
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.
