RM2832   Andradite-Grossular

Distrito de Pampa Blanca, Castrovirreyna, Huancavelica, Perú

Good size and rich aggregate of andradite-grosularia crystals with an intense brown color on the surface, but with color zoning, clearer inside. The exterior of the sample shows a dark reddish-brown tone with very well defined trapezohedral crystals, but inside the crystals have a very aesthetic golden tone. Multi-layered bands ranging from reddish brown to green to gold are shown in the fracture zones of the piece. For this reason we prefer to label it as the andradite-grossular series.

RM2602   Römerite with coquimbite, krausite...

Javier Ortega Mine, Huachuas, Lucanas, Ayacucho, Perú

In this specimen we can observe brilliant aggregates of brown transparent römerite crystals, a very rare iron sulphate. They are accompanied by coquimbite showing an intense violet color under fluorescent light or LED type. They're accompanied by yellow metavoltine/copiapite crystals, along with minor fibrous halotrichite. Note that under the magnifying glass we can navigate in a world of brilliant crystals, some of which of krausite species (yellowish to grey transparent). We left this identification pleasure to the collector. Regarding its environmental stability, this sample has been stored during more than eight years without further alteration.
