Lapis lazuli

Lapis Lazuli, incorrectly called lazurite in the South, is an opaque gem that ranges in color from sky blue to dark blue, bespeckled with gold. These stones were typically cut cabochon and polished to enhance the look of the gold flecks. Lapis lazuli was also crushed and used as an ingredient in making potions of heroism and super-heroism. A typical stone had a base value of 10 gp.
