The Stone
Care & Handling
Clean with warm soapy water and a soft brush. Avoid ultrasonic and steam cleaners unless the specific gem type is known to tolerate them. Store separately from harder stones to prevent surface scratches. Re-check setting security annually if set in jewelry.
Questions
Common questions
Every stone we list undergoes an in-house gemological examination. Where an independent laboratory report (GIA, IGI, AIGS, GRS, SSEF, Gübelin) exists, the report is attached and its reference number appears on the product page. Where a stone is uncertified, we state so plainly and disclose our own findings.
We disclose all known treatments on every product page — no exceptions. Heat treatment, fracture filling, beryllium diffusion, and oiling are each noted where applicable. If a stone is unheated and untreated, we say so and provide supporting documentation where available. We do not sell synthetic or lab-grown material as natural.
Where an independent laboratory report exists (GIA, GRS, Gübelin, SSEF, AIGS), it is attached to the listing and shipped with the stone. For pieces without third-party certification, we provide our own detailed examination report including origin assessment, treatment disclosure, and gemological readings. We never invent credentials we do not hold.
All orders ship fully insured via FedEx or DHL Premium, with signature-on-delivery required. Packaging is discreet and includes a chain-of-custody form. For orders over $10,000 we arrange a bespoke courier route with a custodian hand-off at each transit point. Estimated transit times are 2–5 business days for most destinations.
