This piece of Chrysocolla comes all the way from Ray Mine, Arizona in the United States of America. Chrysocolla is a copper based mineral that is found in the edges of copper deposits. This piece in particular has a really good botryoidal formation to it, where you can see all the individual definition on the bubbles and there aren't a ton of 'globs' on there. They also formed as a druse or druzy giving it a glittery effect when you turn it.
This piece measures approximately 12.0cm long x 7.6cm wide x 3.5 cm tall.
