Bixbite In Rhyolite Gemstone & Information | Gemopedia by JTV | Gemopedia™
As many gem collectors know, bixbite, or red beryl, is one of the rarest gems on the planet. With few faceted gems trickling from its single source in the Wah Wah Mountains of Utah, USA, bixbite in rhyolite is a much more obtainable form of this beautiful gem. Bixbite in rhyolite is the perfect stone marriage, combining one of the rarest gems on the planet with an igneous rock long used as an ornamental stone. While there is precious crystalline bixbite present throughout the rhyolite matrix, cutting to retrieve only the bixbite would yield extremely small stones, with much of this vibrant gem going to waste. Leaving the bixbite in the rhyolite matrix preserves so much more of the material and provides a pleasing contrast of colors - and portrays precisely how these two materials united in nature millions of years ago.
