Collection: Chrysocolla Specimens with Fibrous Malachite
Chrysocolla is a beautiful cyan coloured ore of copper, found in copper and even gold deposits, often with malachite and quartz. It forms in the oxidation zones of copper, i.e. with the weathering of copper deposits comes this ore.
"Chrysos" is ancient Greek for "gold", and "kolla" meaning glue - Guettard of the 18th century wrote, in reference to the ancient sources describing these matters, that if you take a copper-heavy mineral/ore such as malachite, or chrysocolla, and combine it with an organic element such as charcoal, that you can melt it down into copper to use as a solder or glue for working with gold.
This is beyond my expertise - see "Theophrastus on Stones" for more.
Our specimens are beautiful and raw - non polished, not changed. Ours often contain malachite specks and quartz inclusions.
Some even look like mint chocolate chip ice cream! Though tempting, I would refrain from taking a bite if I were you!
Note: this stone is quite low on the Mohs scale of hardness, meaning it is quite soft. Though the part with the quartz is more durable, the rock-face sides can chip even from a fingernail, so best to leave this well out of the reach of children and pets, as well as to secure it in a stable position on an unmoving surface. You can still pick it up and hold it; just don't go crazy, and definitely don't drop it.
