I asked my jeweler about ethical sourcing and they said "all our diamonds are Kimberley Process certified." I looked it up. Here is what that actually means — and what it doesn't.
The Kimberley Process (KP):
Established 2003 to prevent "conflict diamonds" (diamonds funding rebel military groups in civil wars). It requires participating countries to certify diamonds as "conflict-free."
What the KP covers:
Diamonds that directly fund rebel groups overthrowing recognized governments. A narrow definition that was relevant in the Sierra Leone/Angola conflicts of the 1990s.
What the KP does NOT cover:
- Human rights abuses by recognized governments mining diamonds
- Child labor in small artisanal mining operations
- Environmental destruction from mining
- Unsafe labor conditions
- Exploitation of workers who aren't in "rebel" contexts
So "Kimberley Process certified" means the diamond didn't fund a rebel army. It says nothing about labor conditions, environmental impact, or government-sanctioned abuses.
Alternatives for genuinely ethical sourcing:
- Lab-grown diamonds — no mining, no conflict, lower environmental impact than natural mining
- Canadian diamonds — strong environmental regulations, documented chain of custody
- Vintage/estate diamonds — no new mining impact
- Responsible Jewellery Council certified — higher standard than KP, audits supply chains
I ended up buying a lab diamond specifically for this reason. Not because natural diamonds are evil, but because I couldn't verify enough about the chain.


Canadian diamonds have a noticeable price premium too but the chain of custody documentation is genuinely rigorous.
