Kop Krom Mine, Kop Daglari, Erzurum Province, Eastern Anatolia Region, Turkey
A great example of the famous Kop Krom Mine. This kammererite features a nearly isolated crystal over 1 cm. Kammererite is really a clinochlore which is chromium bearing. Chromium is a strong mineral coloring agent and changes the usually green clinochore to this amazing magenta color. Some people refer to it as red or purple, but to me it is a great wine color. Well-formed crystals of this are rare and typically small or drusy as seen covering the matrix in this piece. The main crystals are good sized for the species and locality and the main crystal hosts a textbook example of its monoclinic structure. The plate has two crystals that appear to have been cleaved in pocket as one of them has a tiny crystal formed on its cleaved face. These are not distracting from the main crystals and could easily be trimmed off of the piece.
