all Toggle bracelet seductively on the top

In March 2003, a 3 x 10 x 10-meter pocket yielded specimens of very large albite and milky quartz crystals with patches of fibrous white palygorskite; on this matrix rest beautiful orange-red, gemmy, heavily etched crystals of spessartine to 5 cm, and very sharp, isolated, silvery greenish yellow tetrahedrons of helvite to 5 mm. Tiffany Tiffany Notes Pendant the helvite crystals appear to be pseudomorphs: broken surfaces of some crystals show them to consist of a dull black managanese oxide internally, this having later been overgrown with thin rinds of fresh helvite. The sharp little crystals are liberally strewn over matrix pieces to 30 cm across, but the most appealing specimens are the miniature-sized ones, showing the crisp little helvite tetrahedrons perched on edge, or gently touching in delicate, loose Paloma Picasso Loving Heart bracelet Notes Pendant, on sparkling white quartz or albite. The locality is the Navegador mine (sometimes called the Orozimbo mine, after the name of the farmer who owns the land), Penha do Norte district, Conselheiro Pena, Minas Gerais, Brazil.


The new anatase/rutile specimens offered by Luiz are just as oddly attractive; about 1000 of them were found, Return to Tiffany Double Heart Pendant January and February 2003, in an alluvial deposit in the Cuiaba district, Gouveia, Minas Gerais. At Costa Mesa Luiz had about 50 of the loose crystal groups, between 2 and 3.5 cm tall, all Toggle bracelet seductively on the top shelf of his glass showcase, luring people in from the hallway. These specimens are fragile parallel clusters of bipyramidal anatase crystals, all points pointing up, sides lightly Tiffany 1837 Circles Pendant, to create a cathedral-like aspect. About half of the specimens are simply anatase of a greenish tan, caramel-like color and fairly high luster, while the other half show complete or partial, thin coatings, as if spray-painted, of very bright bronze-colored rutile; some may be partial Tiffany Earrings of rutile after anatase. All are winning thumbnails or toenails of a style of TiO^sub 2^ never seen before (to my knowledge, or Luiz's) from any locality in Brazil or elsewhere.


A few Russian dealers were in attendance at Costa Mesa, including the erudite Dmitriy Belakovskiy of the Fersman Frank Gehry Fish Pendant Museum (dmz@minmuz.msk.su). Here, as usual, were many exotic (though generally beauty-challenged) rarities from the ex-Soviet Union. Most interesting, and not so beauty-challenged after all, were a few cabinet-sized matrix specimens with glistening pale purple coverages of chromian amesite crystals, from the Saranoskii mine in the Urals. The sharp, transparent, hexagonal-prismatic crystals of this rare member of the Tiffany Tiffany Charm bracelet-serpentine group reach 5 mm, and form solid seam linings in massive black chromite, occasionally with pale brown cubes of rutile pseudomorphous after perovskite. Like the much better known, deep green crystals of uvarovite and chromian titanite from this giant chromite deposit, the chromian amesite druses are exposed by the etching-away of the calcite which fills the seams and veins. Dr. Belakovskiy says that he has seen Tiffany box lock pendant amesite specimens from this occurrence with individual crystals to 2 cm long.


Gem-quality forsterite ("peridot") crystals from Suppat, Pakistan are nothing new by now, but Jim Parrish of C. S. Enterprises (jdpsd@san.rr.com) showed me several very sharp, long-prismatic gemmy crystals, to 4 cm, displaying inclusions of long, black, hairlike crystals of ludwigite and vonsenite (verified as such by John Koivala), running vertically in horsetail formations from base to tip. Such included forsterite crystals, Jim said, are very rare from the occurrence; they should be watched for by devotees of the out-of-the-way in gem and/or Pakistani material.
