Our largest gem of the species here, and certainly the most saturated color. This is a riveting, intensely saturated deep blue trillion cut that is nearly clean, and really comes to life and impresses under lights. It has strong display presence and the brilliance of a diamond. Imagine the color of top quality sapphire combined with the dispersion of a diamond! A few small feathers are not visible except under a loupe or in the hyper-high-resolution shot shown here. 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. 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.
