Ruby Red Brookite Crystals On Quartz - Pakistan

Brookite is one of the five forms of titanium dioxide found in nature and forms almost always in association with another mineral, frequently with quartz. This small, unique crystal is typically microscopic, but has been found with larger crystals in some locations. Some of the most beautiful and vibrant brookite specimens come out of Pakistan: it often produces crystals of a brown-orange translucent color, forming flat, computer chip-like projections out of matrix. In some rare cases, just the sim card-like crystals have been found intact, separated from a matrix on their own. These specimens are called "floaters".
