Phenakite - gem Brazilian crystal
stock #21.1-290
Rio Piracicaba
Minas Gerais, Brazil
2.6 x 1.7 x 1.5CM (thumbnail)
price: $360
Late Summer 2021

A hefty (7.6 gram), sharp and glassy Phenakite crystal from old finds in Minas Gerais (Brazil). It is hard to be certain but it certainly looks like this crystal is twinned; most are. The underside (or backside) has a large rehealed and recrystallized area that had been broken long ago. There is an unhealed break on one edge so this is not perfect 360 degrees but the display side looks flawless. The transparency and luster are great in person, this is a good sized and flashy crystal from a locality that has become a classic in Brazil but seems to be no longer producing.

Phenakite on Feldspar, Muscovite with Fluorite
stock #AC-149
Mount Antero, Chaffee County
Colorado, United States
7 x 4.9 x 4.6 CM (cabinet)
price: $140
new year 2021

A classic specimen from Mount Antero, this matrix holds several small Phenakite crystals the largest being 5 mm. Close exam with a loupe finds several other tiny Phenakites and some Fluorite octahedrons. Mount Antero is a remarkable high elevation pegmatite best known for some important finds of Aquamarine. However it has been long known as a source of other minerals, including Phenakites, it is certainly the most important USA locality for this specie.

Phenakite - Untwinned crystals on matrix
stock #18.1-157
Phenakite mine, Khetchel Village, Molo Quarter, Momeik Township, Kyaukme
Shan State, Myanmar (Burma)
4.6 x 3.2 x 2.7 CM (miniature)
price: $280
Worldwide mix summer

Sharp glassy crystals of Phenakite perched on Microcline and Quartz. Most Myanmar Phenakite is twinned, this is the more rare untwinned form of blocky crystals which are in fine condition. Matrix examples are also quite uncommon, most specimens are loose single six sided prisms. A good value for a choice, uncommon type Phenakite.

Phenakite on Adularia
stock #AX-26-011
Mt. Antero, Chaffee Co.
Colorado, United States
3.4 x 2.5 x 1.7 CM (miniature)
price: $100
pre Tucson 2015 update

A nice, sizable Phenakite from Colorado. The old labels say Phenakite on Adularia, they are somewhat transparent and glassy. The main crystal is big for the locale at 1.1 CM, it has a fine glassy luster and is in good condition With magnification it seems to show some twinning and has unusually curved faces formed from several offset faces. A nice affordable Mt. Antero specimen.
