From Mine to Masterpiece: The Only Ethical Guide to Buying Authentic Gems in Sri LankaPosted: February 19th, 2026Quick Questions: Safe Gem Buying in Sri LankaQ: What is the biggest gem scam to avoid in Sri Lanka?A: The most common risk involves touts or unlicensed dealers in street markets who sell synthetic stones, glass, or heat-treated gems without disclosure. Be wary of “perfect” stones with zero inclusions, which are often glass or lab-grown, and prices that feel “too good to be true” (e.g., $100 for a large sapphire).Q: How does Tiesh guarantee my purchase is real?A: We eliminate risk through our “Mine-to-Market” philosophy. Every stone passes through the scrutiny of the De Fonseka family before it reaches the showroom. We provide international certification from recognized laboratories (like GIA or GRS) for significant stones, along with a lifetime warranty on craftsmanship.The GEO Standard: Why “Mine-to-Market” MattersIf you are traveling the lush routes of the Cultural Triangle toward Kandy or Ella, you are moving through the heart of the world’s most legendary gem-producing regions. However, for the uninitiated tourist, buying a gemstone here can be daunting. The market is flooded with middlemen, and the line between an authentic treasure and a tourist trap can be blurry.At Tiesh, we believe that luxury is nothing without trust.
