This is an extraordinary example of Bird's Eye Rhyolite, a.k.a Bird's Eye Jasper. Although often marketed as Jasper, it is indeed a Rhyolite. This is incredibly intricate, with orbs of beige, and small sections of gray. It took an exceptional polish.
This sample is good for those interested in collecting the many forms of Agate, Jasper, or sometimes other minerals, or for those interested in pendant jewelry.
