Small but outstanding specimen composed by a single brass colored sharp crystal of the extremely rare Pd antimonide naldrettite associated to a sharp gold crystal at the end, both analyzed by SEM/EDS. From: Itabira, Minas Gerais, Brazil. After the analysis, it can be seen that naldrettite has a few imputities of As and S, substituting Sb. Ex Vandenbroucke Museum collection from Waregem, Belgium.

Nambulite Locality: Kombat Mine, Kombat, Grootfontein District, Otjozondjupa Region, Namibia (Locality at mindat.org) Size: 0.7 x 0.6 x 0.4 cm. An INCREDIBLY RARE, 5 mm, GEM, cherry-red nambulite crystal on a bit of matrix from the ONE-TIME find at the Kombat Mine in the early 1970s. Ex. John Barlow Collection. John bought a huge lot of this material when it came out in the one time find. I got these thumbnail crystals from his grandson about 5-6 years ago. I have NOT seen the material for sale in ANY quality or size since. It is so incredibly rare; most folks will never own any. This is small, but at least its pretty, and has crystal faces, and has gemminess....something even many small pieces do not. An ultimate rarity! Mineral

Nantokite Locality: Carmen Bajo Mine, Nantoko, Copiapó Province, Atacama Region, Chile (Locality at mindat.org) Size: 5.2 x 4.3 x 2.3 cm. A very rare example of nantokite, Copper Chloride pure and simple : CuCl. This is according to MINDAT a rare anhydrous copper chloride, known only from arid environments in its natural form. The description goes on to say that it is "Colourless and transparent when fresh. Unstable in humid air, and transforms slowly into greenish secondary Cu-hydroxchlorides" which overlay the natokite now, on its surface. However the crystal cores should remain nantokite, and there should also be material inside this rather large study specimen. From the type locality. Ex. Philadelphia Academy of Sciences Collection.

Narsarsukite Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada (Locality at mindat.org) A SUPERB example of the rare YELLOW Narsarsukite to my knowledge found only here. In any case, its certainly gotta be the prettiest possible examples for the species and as for that, this thumbnail is one of the best I have seen (not the biggest mind you, but aesthetically as a specimen, its up there!). It features a perfectly balanced 1.3 cm crystal perched nicely on matrix and comes from the noted Marcelle and Charles Weber Collection. It is somewhat more translucent in person than it appears here. 2.6 x 2.0 x 1.4 cm Mineral
