The gem varieties of quartz have been used as gemstones and other ornamental objects for thousands of years. Green aventurine quartz is a popular lapidary material today, showing an atractive natural green color when polished or when wet. In the past, green aventurine quartz has been miscalled Indian jade although the specific gravity and refractive index can readily identify aventurine quartz from jade.
Some of the earliest primitive stone tools (axes) fashioned by man’s ancestors 2.5 million years ago in the Omo valley in Ethiopia, were made of quartz varieties such as quartzite. These materials were used because of their hardness and their isotropic brittleness which made it possible to shape the tools with relative ease.
The name quartz comes from a Saxon word meaning cross vein ore. The astrological sign of green aventurine quartz is aries. Green aventurine quartz is an alternate birthstone for the month of August.
