Rosell Minerales

Isolated epidote crystal, very faceted and with an intense luster and a deep green color. It comes from this area of Alaska, from the southern part of this North American state. Highly appreciated by collectors.

Size: 3 x 2.5 x 1.9 cm.

Rich specimen formed by numerous spinel crystals showing octahedral form, black colour, very brilliant and well defined faces and edges. Sample is accompanied by the label of Douglas "Doug" Toland, with notes those indicates it could be gahnite or chromite, but the semi-quantitative analysis done with SEM-EDS microscopy shows that it is spinel, not identified in the mine before. It is accompanied by probably grossular and chlorite. A good specimen for the species and for this cold locality.
