Ethical sourcing

We do not knowingly trade in stones linked to armed conflict, forced labour, child labour, or violations of international sanctions regimes. Where the supply chain is opaque or the provenance questionable, we refuse the parcel — we would rather lose a margin than list a stone we can't stand behind.

This policy applies to every gemstone, every diamond, and every lab-grown piece in our catalog.

All natural diamonds in our catalog originate from Kimberley Process-compliant sources and ship with the required Kimberley Process Certification Scheme (KPCS) documentation.

KP is an imperfect framework — it does not cover labour conditions or broader human-rights issues in mining communities — but it is the binding international standard for conflict-free diamonds and we support its continued evolution (including the ongoing debate over broadening its scope).

Following the G7 statement of March 2024 and the EU's 12th sanctions package, we do not sell diamonds of Russian origin to the United States regardless of country of cutting or polishing. For other destinations we follow EU guidance: full provenance documentation required, chain of custody traced to the mine where feasible.

Our diamond catalog is flagged per stone with the `isAvailableInUS` attribute. If you're a US buyer, our checkout blocks any Russian-origin diamond automatically.

We follow the Confederation Internationale de la Bijouterie, Joaillerie, Orfèvrerie (CIBJO) Blue Book standards for treatment disclosure on coloured stones.

Every stone listing declares heat treatment, oiling, irradiation, coating, or absence thereof. Where we say "unheated" we mean a recognised laboratory — GRS, SSEF, or Gübelin — found no evidence of heat treatment. When a lab report is ambiguous, we list the stone as "heat status undetermined" rather than choosing the flattering interpretation.

Every stone we sell has a traceable path from the cutter or mine to your parcel — we know who we bought from, when, and for how much. Provenance paperwork is available to buyers of investment-grade stones on request.

Related: we never under-declare customs value, as explained in our shipping policy. Undervaluation is a cousin of money laundering — it obscures real prices, distorts tax reporting, and damages the legitimate trade we rely on. A seller who undervalues one customs form will undervalue others, and you are right to be suspicious of them.
