Faceted tektite: Some people use fragments of tektites to produce faceted stones. They are usually opaque to slightly translucent and have a pitch black color. They have an elegant appearance similar to jet and are enjoyed by many people. Because of their glassy composition, they have a hardness that is less than optimal for use in a ring. However, in pendants, earrings, and pins, they are less likely to suffer from abrasion or impact. This specimen is a 9 x 7 millimeter rectangular stone weighing about 2 carats that was found in Laos.
