Caribbean Larimar

Larimar is a very beautiful and distinctive-looking stone found in the Caribbean. The stone itself is actually a pectolite (calcium-sodium silicate); however, its blue, blue-green and white hues, as well as the fact that it stems from one location, make it a one-of-a-kind stone.

UCLA Meteorite Gallery Is Out Of This World

Within their collections, many a rockhound has at least one sample of a space rock, better known as a meteorite. Meteorites are truly rare. One meteorite researcher has been contacted by 2,100 people who claimed to have discovered one. Of the 2,100, only seven had found a true meteorite. The rest of the specimens mailed in were hematite or magnetite (iron ores), heavy minerals such as galena, slag from smelting, or just common rocks.
