TC560CT

Spheroidal rosettes of very flattened rhombohedral Calcite crystals, black in color due to the inclusions of fibrous Boulangerite crystals. A typical curiosity of the Maramures mining area, an area that is now only a memory.

Herja Mine, Chiuzbaia, Baia Sprie, Maramures Romania

Specimen size: 13.6 x 10.1 x 7.9 cm

TC55EE

Aggregate on matrix of very sharp lamellar Euchroite crystals, one of them clearly dominant, translucent and with a deep green color. An excellent miniature of this rare species.

Ľubietová (Libethen), Banská Bystrica Slovak Republic (2003)

Specimen size: 1.8 x 1.5 x 0.8 cm

Main crystal size: 0.4 x 0.3 cm

TC180EM

Aggregate of prismatic crystals of Pyromorphite, some of them doubly terminated. The crystals, on a Baryte matrix, have slight curvatures on the faces and edges, are bright and have a brown-yellow color on the prism and an intense yellow on the terminations, a typical combination in many specimens from the locality. An excellent French classic.

Andradite crystals (variety topazolite) with the dominant crystal forms of the rhombohedron, with accessory cube and trapezohedron faces. Translucent, with a bright luster and very uniform honey-yellow color. On a rock matrix, with small spheroidal aggregates of Clinochlore of a very deep green color, almost black. An American classic.
