RM2818 Stibnite and baryte
Baiut, Maramures, RomaniaThick and good size stibnite crystal from this classic Romanian mine. It presents an elongated prism, striated, with an excellent brightness. Very rich in facets in the upper terminal part, with complex bipyramidal faces. Accompanied by baryte cristals as minor matrix. Nowadays it is difficult to find specimens of this quality from this mine. It comes from a former Austrian collection.

RM2817 Stibnite
Baiut, Maramures, RomaniaVery thick and good size stibnite crystal from this classic Romanian mine. It presents an elongated prism, striated, with an excellent brightness. Very rich in facets in the upper terminal part, with complex bipyramidal faces. On the main crystal we observe a group of crystals of the same mineral, finer, that suppose a second crystallization. Nowadays it is difficult to find specimens of this quality from this mine. It comes from a former Austrian collection.
