Basalt is an igneous (now, remember your Geology Class) rock formed when a volcano erupts. These gorgeous natural tube beads are created from a milk chocolaty stone. Each is completely different from the next due its natural origins. There are visible holes and bubbles that create a superb rough tactile sensation. Jewelry made from these beads will be touched a lot. Each tube measures 18 mm long and about 13mm in diameter. The stringing hole size varies from .8 mm to 1.2mm.
Three beads shown for variability.
