Very esthetic and historical specimen formed by crystals of cerussite, transparent to translucent, with an unusual brightness, elongated prisms, rich in faces and some twins. Closely observed, it becomes a crystallographic pleasure. From a classic Moroccan mine from where nowadays is not easy to find samples with this quality.
Aesthetic and historic specimen of anglesite, formed by a well developed tabular crystal, lanceolated, very rich in faces, with various rhombic prisms facets and striated pinacoids. 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.
First appointment for this Moroccan locality. This lead, iron and rich copper sulfate has been analyzed by SEM-EDS, we will send results to the buyer. Beaverite-(Cu) forms yellow earthy masses formed by lenticular crystals. It is accompanied by fibrous malachite crystals and azurite crystal aggregates. In the matrix we have observed the presence of cerussite. Only the combination of colors and species in this sample is aesthetic itself.

A rich group of azurite crystals partially replaced by malachite. Azurite crystals show tabular and lenticular shape forming rosettes, with an intense blue color. Malachite shows the shapes of the crystals of azurite those has been partially replaced and fibrous to acicular crystals with a delicate velvety aspect very aesthetic.
