Aqua stone is created in a lab, combining quartz, glass, and stone powder. The components are compressed with heat to make this beautiful stone with the hardness of quartz. Delicate translucent mint green looks like chalcedony (but it isn't). The briolette is a 12x8mm flat faceted teardrop. Beads are meticulously wire-wrapped for beauty and security. All silver is sterling. 1-1/4" (30mm) long from the top of the lever backs. Gift-ready in either an organza bag (default) or gift box upon request. Packaging styles change with availability.
