Rosaline

Rosaline is a pink stone found in very large quantities (usually cut in one pound (two kilogram) blocks for trading), or in crystals exhibiting trichroism (three colors in the gem, each viewed from a different angle), often purple, blue, and red, or purple, green, and red). The opaque pink variety is soft and will be tumbled or cut cabochon while the harder crystal form will be faceted by a lapidarist. Large crystals have brought higher prices when fashions have turned to brooches and rings adorned with rosaline. Rosaline is also known as unionite, thulite, or pink zoisite.  A typical specimen has a base value of 10gp.
