Effenbergerite Locality: Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa (Locality at mindat.org) Size: 2.2 x 1.8 x 1.2 cm. Any Effenbergerite is a good Effenbergerite, considering how rare this species is, and how few specimens ever come to market. This is small, but it has several spots of eye-visible Effenbergerite crystallization upon it and should be considered significant enough to add to any rarities suite. TYPE LOCALITY. Mineral

Absolutely gemmy crystal of the very rare mineral eifelite in a very small matrix. Eifelite is an extreme rarity from Eifel. In all the active collecting at Bellerberg, eifelite has only been found once. Eifelite has only been found in Eifel worldwide (Bellerberg, Ettringen, Eifel Mountains, Rhineland-Palatinate, Germany).

Eirikite, Leifite (The greatest diameter is about 2.5 cm) Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry; Carrière Mont Saint-Hilaire), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada One of the moons of Jupiter as seen from the magic mountain. According to László Horváth (private communication), a CMN specimen from this find was found to have both eirikite and leifite. (But this particular specimen has not been analyzed.) Regarding the color: This is a rather deeply colored example from this find. The color is fairly accurate. See Lapis July-August 200 p. 11 for an even more deeply colored example. Mineral

Eitelite Locality: Westvaco mine, Green River formation, Sweetwater County, Wyoming, USA Dimensions: 3.5 cm x 1.4 cm x 1.1 cm Description: Eitelite is an extremely rare carbonate mineral species, found in masses of grains or smears at a very few locales. Interestingly it was named after the scientist who first made it in the lab, rather than a natural crystal or example. Thus, natural, large eitelite specimens are unprecedented, even more than with most rare species, and this surprise new find released at the 2012 Tucson show was a big surprise for those who collect the rarities. These attractive specimens seem to be true crystals of eitelite, though grown in conjoined, lamellar masses. The top may be a contacted termination, where it grew against a constricting matrix of the pocket. Mineral
