In-game description
"Star Diopside is the most prized form of a hard, durable gemstone that is rarely found in attractive colours. It is usually too dark for beauty, however mountain and streambed-pebble crystals of a pale green hue make attractive stones such as diopside.  When a gem is found that is darker green it can be cut in such a fashion so to produce four- or six-rayed stars."
