Sunstone Gemstone Beads from Rings & Things: Sunstone beads consist of feldspar crystals that were formed in molten lava, then discharged onto the surface of the earth by volcanic eruptions. As the lava weathers away or is broken up, the crystals are released. This semiprecious gemstone is also known as aventurine orthoclase, heliolite, or aventurine feldspar, and it varies in color from golden to orange to red-brown. Sunstone beads can be transparent or translucent, and can provide metallic glints due to sparkling inclusions. These semiprecious beads are believed to strengthen life force, bring luck, instill optimism, and increase vitality. Sunstone is also thought to bring luck and romance to the wearer, and is believed to help liver and kidney health. Sunstone is the state gemstone of Oregon, USA, where some sunstone rough is mined.
