In this episode of Secrets Behind the Sparkle, we examine the difference between a gemstone that is genuinely exceptional and one that is simply expensive.

Some gemstones look full of promise. They may come with an impressive story, attractive paperwork or the expectation that cutting will reveal something exceptional. But appearance and potential do not always translate into quality or value. In this episode, we explore three hidden risks behind a significant gemstone purchase—and why knowing when not to buy can be just as important as knowing what to choose. I also share the story of a piece of Tanzanian sapphire rough that appeared worth cutting, until an experienced cutter identified the silk, darkness and likely result beneath the surface. His advice was simple: do not cut it.
