RM1537   Quartz pseudomorph after orthoclase (Karlsbad twin)

Malpartida de Corneja, Ávila, Castilla y León, Spain

These specimens were collected in an outcrop situated between the villages of Malpartida de Corneja and Casillas de Chicapierna, in Ávila. They are floating crystals of twinnen orthoclase (Karlsbad) those have been partially or totally pseudomorphized by quartz. They present visible forms of the twin, with altered faces with curious cavities. Some specimens still preserve an orthoclase crystal core. This pseudomorphosis is very unusual.

RM2013   Anatase with quartz

Moro Quarry, Oteruelo de la Valduerna, Santiago de Millas, León, Castilla y León, Spain

Druse of small quartz crystals, some doubly terminated, partially covered by white kaolinite. Peppered by several anatase crystals, with dipyramidal faces, truncated by basal pinacoid. Very sharp, translucent and with a toasted honey tone. Very aesthetic and rare in the market.
