Rhyodacite Gemstone Beads

Our rhyodacite beads are composed of three gorgeous components: the first is a subdued, opaque taupey-gray color, the second is a soft, opaque rose pink, and the third is a stunning, transparent, bright periwinkle blue. The lovely, delicate colors of these rhyodacite beads are a beautiful contrast to the rugged rocky pattern.

Rhyolite, very similar in composition to granite but with much more finely grained crystals, is composed mainly of silicon-rich quartz, feldspar, mica, and hornblende, and is formed when lava erupts from a volcano and then cools very quickly, giving portions of the stone a glassy appearance.
