Swirling greens, browns, and oranges in these impressive 12mm round Rhyolite gemstone beads. Rhyolite is also erroneously marketed as rainforest jasper. They're igneous extrusive rocks formed from magma. The magma cools so quickly that microscopic crystals form the stone, and then over time larger crystals form within the rhyolite, offering small windows of translucent quartz or other minerals.
These are very nice quality, well cut beads. However, due to the varying mineral mix within rhyolite, some unevenness in the shape of the bead may occur when cutting. And you may have a bead with a chipped drill hole.
