Malachite - Loose Stones

A deep green, opaque crystal known for its unique swirling patterns, which comes as a tumbled loose stone ranging from small to medium-sized. 

Malachite crystals have been used all throughout history, in Greece and Egypt, as a stone of protection that cleanses negative energy. Some acknowledge it as the "stone of transformation," since it's said to deeply heal the heart and cleanse its holder's energy.
