Angelar's skin

Angel's Skin is not a mineral but a fine pink coral suitable for use in jewelry, usually found in the shallow tropical seas upon isolated reefs or atolls. It is delicate and easily shattered unless properly treated and mounted. In the Realms, it is slowly sun-baked on large, flat rocks to drive off water and tiny animal life (dead from lack of water but still present in the coral) that otherwise would give it an offensive odor and reduce its value for adornment. A typical specimen has a base value of 100gp.
