Every specimen we sell is logged with its mine or locality where known, and every specimen that has been enhanced in any way - dyed, heat-treated, irradiated, stabilized with resin, or lab-grown - is labeled as such on its tag and on this site. Nothing is sold as natural unless it is.
Treatment is common in this trade and is not a defect - citrine is almost always heat-treated amethyst, and most blue topaz is irradiated. The problem is not the treatment, it is a customer finding out about it after the sale. We would rather you know before you buy.
Specimens are acquired from small dealers and estate collections, then re-verified against our own reference set before pricing. Anything we cannot confidently identify is sold as "unidentified mineral" rather than guessed at.
