Cassiterite

Cassiterite is a tin oxide mineral (SnO2) and is the primary ore of tin. It is typically found in granitic rocks and alluvial deposits and has a high specific gravity due to its dense composition. Cassiterite forms under high-temperature conditions and can exhibit a range of colors, often with a resinous or adamantine luster.
