About Cyprine (of Berzelius)

Cyprine is a sky-blue to pale blue copper-bearing variety of vesuvianite (idocrase) first described by Swedish chemist Jöns Jacob Berzelius from specimens at Télemark, Norway. Its delicate cyan-blue color—rare among vesuvianite varieties—is caused by trace copper substituting in the crystal structure. Transparent faceted specimens are exceptional collector rarities, as the mineral rarely occurs in gem-quality clarity.
