A first class specimen of beautifully crystallised Ilvaite shallowly embedded in various faces of a creamy to colourless, double terminated scalenohedral Calcite crystal. This cabinet specimen is from the Dalnegorsk mining region in Primorsky Krai, Far-Eastern Region, Russia and is attached to remnants of the matrix embedded in the back faces of the scalenohedral. Ilvaite, an iron and calcium sorosilicate forms impressive, perfectly terminated, opaque black crystals with a bright lustre, the largest measuring 2.5 cm long. Under LWUV the Calcite fluoresces bright scarlet. An superb specimen accompanied with a Don Edwards (Commercial Road, Tideswell, Derbyshire) label.\n

Calcite from Dalnegorsk, Russia
Dalnegorsk is one of those mineral names that experienced collectors read almost as a guarantee of sharp form, strong association, and geological complexity. Calcite from the district is not a single “look,” but a family of looks: water-clear trigonal prisms, pale honey to colorless scalenohedra, pink manganese-bearing crystals, flattened rhombohedral plates, nailhead forms, and complex multi-generation pieces in which one calcite habit overgrows another. The best examples have a crispness that feels almost engineered—bright faces, glassy transparency, and a habit vocabulary broad enough that two Dalnegorsk calcites can appear to have come from different countries.
