Crystals in the orthorhombic system have 3 axes: CHRYSOCOLLA each of different length, so the crystals are By Susan Celestian generally tall or squat, with a diamond-shaped cross-section. See Figure 1. Chrysocolla got its name from the copper alloys FIGURE 1 Forms of used to solder gold. In Greek, the solder is the Orthorhombic χρυσός κολλα (chrysos kolla), meaning "gold glue". System As illustrated in the This is a mineral that is found in many, many Orthorhombic system localities throughout Arizona. And it is often diagrams, all three confused with Turquoise, a hydrous copper axes are of different lengths. Diagrams by aluminum phosphate hydroxide. Susan Celestian PRISM PYRAMID Field test to distinguish chrysocolla from turquoise: As long as the chrysocolla is not silicified (combined with quartz), one can touch one’s tongue to the sample. Chrysocolla will absorb water, and one’s tongue will stick to the chrysocolla; while there will be

no effect on turquoise. Give it a try!

Chrysocolla most typically occurs as thin veins or coatings, massive or botryoidal (‘bubbly’) veins and CROSS-SECTION CROSS-SECTION coatings, or fibrous tufts -- never as large crystals. Occurring as a secondary mineral in the oxidized Desireable specimens are coated with a coating of drusy quartz. zone of copper deposits, chrysocolla is a minor ore of copper.
