It presents an excellent transparence and good brilliance. It is disposed on a galena matrix accompanied by other crystals of the same species. A pleasure to enjoy the crystallography of the piece. An ancient specimen of the former Manchión collection.
Very rich and brilliant specimen of anglesite, formed by several prismatic crystals, with transparence, brilliance, defined faces and edges and colorless. A pleasure to enjoy the crystallography of the species. They are partially covering a vug in a galena matrix. A sample from former Daunis collection (Barcelona), with many years on his "shoulder".
Rich group of so called arsenatian vanadinite showing defined edges and curved faces, barrel-shaped and many of them doubly terminated, with the characteristic color of this variety. These samples appeared on the market in the late 1970s as pyromorphite, until they were correctly determined by XRD and SEM-EDS analysis. This specimen has been analyzed, just for info, showing As 3.3%weight and 9% in V. Old specimen, nowadays rare to find.
Superb and brilliant specimen formed by botryoidal aggregates of malachite, of intense green color, and covered by small hyaline quartz crystals. Quartz gives it this aesthetic brilliance. Matrix is formed by a stockwork of altered chalcopyrite. Malachite specimens from this locality and with this shape are unusual.
