Keyite is a mineral with the chemical formula Cu2+3Zn4Cd2(AsO4)6 · 2H2O. The name comes from Charles Locke Key (born 1935), an American mineral dealer who furnished its first specimens.Keyite is monoclinic-prismatic, meaning its crystal form has three unequal axes, two of which have 90° angles between them and one with an angle less than 90°.Keyite belongs to the biaxial optical class, meaning it has more than one axis of anisotropy (optic axis), in which light travels with zero birefringence, and three indices of refraction, nα = 1.800, nβ, and nγ = 1.870. Being a very rare cadmium copper arsenate, keyite is only found in Tsumeb, Namibia in the Tsumeb mine, a world-famous copper mine known for its abundance of rare and unusual minerals.

| - La keyita és un mineral de la classe dels fosfats, que pertany al grup de l'alluaudita. Rep el nom en honor d'un important distribuïdor de minerals nord-americà, Charles Locke Key (1935-). (ca)
- Keyit ist ein sehr selten vorkommendes Mineral aus der Mineralklasse der „Phosphate, Arsenate und Vanadate“. Er kristallisiert im monoklinen Kristallsystem mit der chemischen Zusammensetzung Cu2+3(Zn,Cu2+)4Cd2(AsO4)6(H2O)2 und ist damit chemisch gesehen ein wasserhaltiges Cadmium-Zink-Kupfer-Arsenat. Keyit entwickelt bis 2 mm große, spitz zulaufende Kristalle, die prismatisch nach [001] bis tafelig nach {010} ausgebildet sind und zu subparallelen bis garbenförmigen Aggregaten zusammentreten. Größere „Kristalle“ stellen Aggregate aus in subparalleler Position verwachsenen Täfelchen dar. (de)
