Chrysocolla with Fancy Fern Leaves Pin/Pendant: SS2. 75" H x 2. 5" W x . 5"D Chrysocolla derived from the Greek chrysos meaning "gold," is a copper mineral. Crystals are very rarely seen, but it is frequently intergrown with other minerals such as quartz or opal. This results in a harder, more resilient gemstone, as pure chrysocolla is soft and fragile. Its copper content is responsible for chrysocolla's range of bright green to blue hues.
