The Atlas standard
Five things we promise on the listing, in the package, and after the sale — every time.
Earth-mined. Never lab-grown, never synthetic, never simulated. The only kind of stone we sell — without exception, since 1995.
Country and city when we know it. “Most likely from” when the chain is generalized. Never invented.
Heat, diffusion, dyeing, fracture-filling — declared on every listing. Or marked untreated, when we can confirm it.
Hold every stone in your own light. Return for any reason, free. No questions, no restocking fee. We pay the shipping.
From the US, end-to-end tracked, fully insured to your door. 1–2 days to pack, 2–5 in transit. GIA certification on request.
