Moonbar

Moonbars are pearly white, opaque gemstone crystals found in desert and tropical areas of the Realms. Moonbars are naturally large and rectangular (with curved corners) and have a smooth, shiny surface, so when found and washed clean, specimens are immediately suitable for use as gems; cutting is only required when fragments are found. The largest known moonbar serves as the lid of an unknown king's casket in a barrow on the Trollmoors, and is almost seven feet (two meters) long, but most are approximately a foot (thirty centimeters) long and four inches (10 centimeters) wide. A typical specimen has a base value of 1000gp.
