RM2011   Schorl

Good schorl specimen from the clssic locality of Cap de Creus, Girona. Some crystals showing a developed and faceted prism and terminal faces, some of them with good thickness.

RM2009   Vesuvianite

These mines are located in the heart of Massís del Montnegre, in Catalunya, and it is a classic for mineral collectors. The "vesuvianas" are found mainly in the outer zone of the mines. In this old specimen we can enjoy a radial aggregate of vesuvianite crystals, of good size and with the beige-greenish color that characterizes them in this locality. In a small vug we can see greenish transparent and well formed crystals of the species.

RM1991   Almandine with schorl and feldspar

An old piece from el Cap de Creus (Creus Cape), in Girona.

RM1974   Čechite

These specimens were found in a outcrop close to Maria Magdalena mine, close to the beautiful town of Ulldemolins (Tarragona, Catalonia). Probably, these crystals are the most defined crystals of Čechite worldwide. They are brilliant, black color and show a tabular shape defined by different order orthorhombic prisms and pinacoidal faces. Disposed very aerial on a fluorite matrix.
Čechite is very rare lead iron vanadate that is only found in a few places in the world and it is the first citation in the Iberian peninsula.
SEM-EDS and EPMA analysis show that, in some cases, on the crystal surface there is Cu2+ has been formed but the crystal is pure PbFe2+(VO4)(OH). In most specimens (all) from other localities the presence of manganese is important, but these specimens are Mn free. We will send more details to the buyer.

Size: 4 x 2 x 1.8 cm.
Main crystal: 1 mm.

RM1947   Heterosite-Purpurite

These samples of heterosite come from a classic area for the Catalan mineralogy such as Cap de Creus, in Girona. They belong from a former collection and were collected, according to the owners, by the 70s of the last century. Currently, in the Cap de Creus area, it is strictly forbidden to collect absolutely anything. These samples show aggregates of brownish-black tones, with a certain brightness, with layers of violet color and embeded in a pegmatitic matrix. No acid applied.
Bareche, in his work "Els Minerals de Catalunya, Segle XX" (2005), indicated the presence in this area of several rare Mn and Fe phosphates. He indicated that the purpurite was found in a single outcrop as small masses of violet and brownish color, along with heterosite from brown to black. From these specimens, several fragments of violet tone have been analyzed. The results have indicated that iron is predominant, with a ratio Fe:Mn, 2:1, consistent with heterosite. We do not rule out that purpurite (Mn> Fe) could be present, as member of heterosite-purpurite series.

RM1841   Anapaite

This specimen presents a good size nodule, with an internal part with septaria structure, completely covered by very brilliant and transparent green crystals of this rare iron and calcium phosphate.
