Mykaro

Mykaro is the common name for smithsonite, a massive gemstone found in many hues (yellow, straw yellow, pale brown, reddish brown, green, blue, blue-green), as crystals or as crusts up to two inches (five centimeters) thick in rock cavities. Mykaro is soft and tough when found as a crust, but brittle in crystal form. It is usually cut cabochon, particularly if it is patterned with thick bands of varying colors, but is sometimes faceted. A typical specimen has a base value of 50gp.
