Rosaline

Rosaline is a stone found in massive, soft quantities (usually cut in one pound (two kilogram) blocks for trading, and later cut cabochon), or in harder crystals of vivid trichroism (three colors in the gem, often purple, blue, and red, or purple, green, and red). The trichrosim is cut in facets. Large crystals of this latter variety 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.
