Abstract/Description: ‎Cu2CO3(OH)2 and ‎Cu2H2Si2O5(OH)4 - Mohs Hardness: 3-4. Chrysocolla, a copper silicate, blends well with Malachite, a copper carbonate and the combination is often cut into cabochons for jewelry. Beautiful blue chrysocolla and deep green malachite are found in the oxidation zone of major copper deposits. Chrysocolla-Malachite is fragile and is usually stabilized before cutting into cabochons. The name "chrysolla" was derived form the Greek words "chrysos" and "kolla" which translate as "gold" and "glue." It earned its name because it was often used as a gold soldering agent.
