Luriyl

Luriyl, also known as apatite, is a soft stone, easily worked and widely used. Found in crystals, it yields attractive faceted gems of vivid yellow, green, yellow-green, and (rarely) blue and purple. Large specimens of blue or purple command high prices and are much used in necklaces, pendants, belts, and insets in gowns or cloaks. A typical specimen has a base value of 50gp.
