Nelenite Locality: Trotter Mine (Lehigh Mine), Franklin, Franklin Mining District, Sussex County, New Jersey, USA (Locality at mindat.org) Size: 4.0 x 2.8 x 1.7 cm. Nelenite is a very rare silicate found in only two localities worldwide, both in the United States and this specimen is from the Type Locality - the Trotter Mine at Franklin, New Jersey. Brown nelenite is richly dispersed on both sides of the matrix, which includes metallic, black franklinite. Ex. George Elling Collection, a noted Franklin/Sterling Hill collector. Mineral

Nenadkevichite Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada (Locality at mindat.org) This specimen contains what are by far and away among the largest reported crystals of the species, as do other specimens from the remarkable find which are shown below. These crystals are to 6-8 mm in size and are nice and fat as well. Previous examples have usually been at the 1-2mm size level or less! The matrix was extremely loose in the pocket and so nearly all recovered specimens are thumbnails (from which I cherrypicked the best 10 or so - below). This was one of the two best larger specimens of Nenadkevichite which I was able to obtain from Gilles Haineault , which were collected by him in July of 2003. However, with delays for prep and analysis, I only heard about these amazing specimens this summer. The identity has been solidly confirmed and they stand as exceptionally beautiful and significant examples of the species. 4.4 x 3.4 x 2.0 cm Mineral

Nepheline, Schorlomite Locality: Bou-Agrao Mt., Tamazeght complex, High Atlas Mts, Khénifra Province, Meknès-Tafilalet Region, Morocco (Locality at mindat.org) Size: 6.0 x 4.4 x 3.8 cm. An excellent and uncommon combination specimen from the High Atlas Mountains of Morroco - Bou-Agrao Mt. A large vug is lined with sharp, hexagonal, grayish-white nepheline crystals to 1.8 cm and nicely complimentary, lustrous, jet-black crystals of schorlomite. The textabook, dodechedral crystals reach 1.5 cm. Schorlomite is a rare garnet group member and much of the material labeled "schorlomite" is, strictly speaking, titanian andradite. Excellent, highly representative combination material of the species and locale. Mineral
