Imagine the color of top quality sapphire combined with the dispersion of a diamond! That's the allure of this rare collector's stone from the United States (in fact, it's the state gemstone of California, so makes for a unique conversation piece). Benitoite is a very rare TITANIUM-containing species that comes in large crystals only from this one aberrant geological district. The mine is closed, so good sized gems will always be rare commodities in the market. This is a very desirable square cushion cut that is superbly bright and clean and about as good as you can get for the species in absolute quality. From the collection of former mine owner Bill Forrest. We have seen quotes on pieces of this quality, and size, at $10,000 per carat retail.
