Mohs Hardness of 2 with a monoclinic crystal structure
Chrysocolla generally appears in clusters like grapes or in a crust. More often than not they are intergrown with Opal, Quartz, Malachite, Azurite and/or Turquoise.
When intergrown with Malachite and Turquoise, it is referred to as Elilat Stone. And when mingled with Quartz, it is referred to as Stellarite, which is an entirely different stone from Zoisite, which appears very similar. Gem Sillica is what Chrysocolla is known for in it’s gem state.
