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

€560 / US$605 / ¥88340 / AUD$940

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.
