RM468   Calcite with dolomite

La Cuerre mine (La Florida mines), Rionansa (Herrerías), Sierra de Arnero, Asturias, Spain

Calcite specimens from la Florida mines are known and valued worldwide. In this sample we have a complex twinned escalenohedron, "doubly terminated", with combination with the rhombohedron. Transparence is excellent, with defined striated faces and delicate edges. It has a delicate yellow to orange tone. In this specimen we can see, in the rear, the contact with the dolomite matrix where crystal had growth and an exfoliation, that does not affect the aesthetics of the sample.
specimens appeared accompanied by pink dolomite, at level 6 of this mine. On one side there is a hoppered cavity in which it was disposed another group of crystals. A huge size and excellent specimen from this classic Spanish locality.

Size: 8,3 x 5,8 x 4,4 cm.
