Lapis lazuli

Lapis Lazuli is an opaque gem that ranges in color from sky blue to dark blue, bespeckled with gold. Incorrectly called lazurite in the South, lapis lazuli is usually carved cabochon and polished to show off its gold impurities. Crushed lapis lazuli is used in making potions of heroism and super-heroism. A typical stone has a base value of 10gp.
