Scainiite Locality: Strieborna vein, Ludovit Mine, Dúbrava, Northern Low Tatra Mts, Žilina Region, Slovakia (Locality at mindat.org) Size: small cabinet, 7.0 x 4.5 x 2.4 cm Scainiite Scainiite is a VERY rare lead-antimony sulfide. The mineral was known only in a few, poor specimens from this locality until recently (I am told these were collected in 2009), as you can see from the few photos of smears on a rock, shown on MINDAT. Even at its type locality, 3 mm crystals would be considered large. Here you have, however, 7 cm-long carpet of flatlaying crystals on matrix. They are embedded, and grown in aggregate, but still are huge examples of the species and this is one of the more rich specimens recovered. Mineral

Kermesite, Schafarzikite Locality: Pernek-Kriznica, Southwestern Slovakia, Slovak Republic (TYPE LOCALITY) Size: small cabinet, 6.2 x 3.5 x 2.2 cm Schafarzikite Xls on Kermesite Xls This is one of those weird minerals that, having never seen one for sale and finding the name unpronounceable, I admittedly just bought on trust that it is as rare as my supplier thought. I got it from Josef Vajdak of Peque Rare Minerals, in response to the usual "show me something neat and rare" question I ask him at shows. He says it is really good for what it is, and I will cede to his wisdom on the point. Josef is, after all, one of the better known Czech mineralogists and has a Czech mineral named after him, even. So, I figure he knows his minerals from the region! Comes with a copy of a scientific article on the find (in Czech) and an XRD analytical result set including photographs and data. 6.2 x 3.5 x 2.2 cm Mineral

White acicular schaurteite crystals in a nice crystal cluster. Schaurteite is a very rare germanium mineral only known at Tsumeb (Tsumeb Mine, Otavi Highlands, Namibia), which of course is the type locality. It has 3 labels from old collections, see photos, including the D.Cathcart label. Schaureteite was labeled as RR (very rare, single occurrence with more than 10 specimens sknown) in Gebhard Tsumeb book. Mineral

Schiavinatoite Locality: Antsongombato gem mine, FKT Antsentsindrano, Andrembesoa Commune, Betafo District, Vakinankaratra Region, Antananarivo Province, Madagascar (Locality at mindat.org) Size: 5.6 x 3.9 x 3.5 cm. This is a newly named (1999), extremely rare mineral from Madagascar. Embedded in quartz are sub-metallic, taupe-gray crystals to 2 cm in length. I obtained this in exchange from Dr. Pezzotta, who specializes in the minerals of Madagascar and I think could be safely considered the authority on finely crystallized rarities here. He told me these are among the largest fine crystals known for the species. I certainly have seen nothing comparable on the market, and for that matter you don't see much of it at all on the market.

Bustamite Locality: Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa (Locality at mindat.org) Size: 9.4 x 5.3 x 4.5 cm. Bustamite is actually fairly uncommon for the Kalahari district, and this is a rich specimen, with intense color. The soft pink hue is not pale…it’s actually quite strongly colored for a pastel hue. Charlie rated this highly, and said it was an unusually thick piece with the kind of color treasured for lapidary use, carvings and such. Ex. Charlie Key. Mineral
