This large marquis shaped cabochon of Birdseye Rhyolite has beautiful patterns with a high gloss polish. Birds Eye Rhyolite refers to some spherulitic rhyolites. Rhyolite was named "streaming rock" because of its beautiful bands, bubbles and crystal-rich layers that form as lava flows onto the surface of stone and moves forward. Rhyolite can look very different, depending on how it erupts.
