RM2988 Fehrite and devilline
Les Ferreres mine, Rocabruna, Camprodon, Girona, Catalunya, SpainFehrite is a recent new species found in Almeria (Spain). Some years ago (2012) we identified this species in the Les Ferreres mine (Camprodon) but unfortunatelly we didn't have enough sample to finish detrmination and structural studies. Recently we found some more samples and the characterization was carried out based on the results obtained from the application of various analytical techniques: SEM-EDS, Raman and X-ray diffraction. Les Ferreres mine is the second locality worldwide for the species. We will send all reports to the buyer.
In this Catalan mine, fehrite appears as elongated elongated tabular to fibrous crystals, with a delicate bluish-green tone, and fibrous terminations. Usually, it is accompanied by devilline (blue) and brochantite (green). It is the magnesium analogue of ktenasite.
Size: 2.4 x 1.4 x 1.3 cm.

RM2965 Pitticite, 'Ganomatite' - Scorodite, Galena
St. Andreasberg, Braunlage, Goslar, Lower Saxony, GermanyThis is another one of those specimens from old collections, as evidenced by the various accompanying labels, that contain discredited or dubious mineral names. Even so, the historical and scientific interest it presents has made us offer it.
In the piece we observe a core of galena with halos of alteration of the vein in the socket. In the cavities we find numerous well-formed crystals of cerussite. And in some areas we observe greenish and honeyed tones probably corresponding to pyromorphite, but also to possible scorodite. The 'ganomatite' is considered a scorodite with impurities, while the pitticite is a questionable species formed by amorphous hydrated iron arsenate. Although this last mineral is currently accepted, it is questioned.
Size: 5.4 x 4 x 3.9 cm.
Found in ±1977.
