Solar Quartz Natural Slices have a vitreous luster with a crackled ice appearance within an opaque stone. Each gem is unique with a colorless quartz / predominantly milky quartz body showing mossy and crystal internal features. These solar quartz are cut from natural material of cave stalactites and have organic edges. The center section is polished to show the unique features of the stalactite interior. Wonderful bead with an organic appeal!
