The sparkling gemstone, Sunstone is the gemstone of the week. Sunstone is a member of the feldspar family. When veiwed from certain angles, it has a brilliant, spangled appearance. This optical effect can be from tiny scales of red hematite which are irregular in shape. This gives it a look similar to aventurine and it is sometimes called aventurine-feldspar. Some crystals contain pyrite which gives it an extra flash of sparkle. Darker stones contain copper. Sunstone is formed in molten lava and then thrown out to earth by a volcano. As the lava weathers, or breaks up, Sunstone crystals are released. It is a sodium calcium aluminum silicate.
Sunstone is a relatively hard stone with a hardness that varies from 6-7.2.. Also called, Heliote, which comes from the Greek word “helios” and “lithos” meaning stone, Sunstone is the state stone of Oregon.
