99.9999% Pure Crystalline Germanium Metal Element, 2 Grams in Sealed 2ml Glass Ampule - Collection, Display, Education

This germanium comes from an actual single crystal boule manufactured for the electronics industry. Each piece is a single crystal, meaning that the atoms are organized in their natural structural formation. Germanium is a rather rare element, and is typically found during the mining of other minerals. Like its more common cousin silicon, it is a metalloid and a semiconductor, and is mainly used in microchips and transistors. Being rare and in rather high demand, it is currently worth more than silver. It is brittle like sulfur or carbon, but has some metallic properties, most obvious of which is its appearance.
