Topaz is one of the most versatile natural gemstones: a hard (8 on the Mohs scale), brilliant crystal that ranges from perfectly colorless through sky and Swiss blue to champagne, golden “imperial” and rare pink hues. Its excellent clarity and vitreous luster make even modest stones remarkably lively — and larger crystals spectacular.Our topaz collection is one of the largest at GEMIC Institute, spanning faceted classics, cat’s-eye rarities and unusual natural colors. Brazil is the historic heartland of fine topaz, with additional production from Africa and Asia. Every stone we offer is natural, photographed and filmed individually — the listing shows the exact gem you will receive.Each topaz is examined by our accredited gemologists in Siem Reap and accompanied by its laboratory certificate stating species, treatment status, weight and dimensions. All pieces are unique; once a stone finds its owner, the listing closes forever. Worldwide tracked shipping and a 30-day return window apply to every order. Can’t find your ideal topaz?
