How can I avoid gemstone scams?

You can avoid gemstone scams by buying only from reputable, long-standing dealers and also requiring an independent certification report from recognised gemmological laboratories like the GIA, Gübelin, or SSEF.

Do not trust a seller’s internal report alone, or their talk about quality, just because it sounds confident. Instead, study the usual warning signs like pricing that appears unrealistically low, pushy sales tactics, or stones offered in tourist locations with no verifiable documentation. If you familiarise yourself with common treatments, for example, glass filling or beryllium diffusion, you reduce the risk a lot.
