A variety of Minerals
What is Connellite?
Connellite is a rare mineral occurring in transparent blue. These minerals can be found in spiky formations with delicate spines and fibers. Connellite is named after chemistry professor, Arthur Connell, from Edinburgh, Scotland. This mineral has since been discovered in a couple of hundred locations over several continents, though in low concentrations.
