Grossular on Diopside - USA classic
stock #20.1-292
VAG Mine, Lowell & Eden
Vermont, United States
3 x 2 x .9 CM (thumbnail)
price: $390


An American classic. The most desirable of the famed "Eden Mills" garnets are the gemmy red-orange crystals on contrasting green Diopside crystals. This legendary quarry has been closed for decades, this style of Grossular is unique to the lower reaches of the site, it is quite different from anyplace else on earth. This is an especially cute thumbnail the small Garnet is an inter-grown trio of crystals that contrasts well with the matrix. In fine condition damage-wise by naked eye but with good magnification a chip is seen. Not for perfectionists but that keeps the cost well below normal market for a specimen of this sort.

Anglesite - gemmy crystals
stock #20.1-291
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oriental Region, Morocco
1.7 x 1.1 x .8 CM (thumbnail)
price: $90


A cute thumbnail of light yellow Anglesite crystals in a slightly radiating cluster. These are transparent, glassy and sharp, this is also fluorescent an orange-red in long wave UV. The color is fully natural, some Anglesites were color enhanced in Morocco by dipping into a chlorine bleach. The results were deeper color but also an odd luster, this one is completely real. In good condition, all the terminations are perfect, there is contact/roughness on some of the lower sides only. Touissit has been closed for decades now but it was once a magnificent locale for fine lead secondaries.

Smithsonite - well-crystallized
stock #17.1-070
Tsumeb
Otjikoto Region, Namibia
3.7 x 3.6 x 2.7 CM (miniature)
price: $280


Small miniature of well-formed, transparent elongated Smithsonite crystals from the great Tsumeb Mine. Remarkably this delicate specimen is perfect, no damage seen even under good magnification. In person these are very glassy and have a faint hint of yellow color, and at some angles the reddish matrix seen through the crystals gives a pink hue. I would call this close to colorless. Tsumeb was the source of so many colors, habits and associations for Smithsonite. This piece is really esthetic, it has a little Galena on the back side but the front is all nice Smithsonite.

Corundum var. Sapphire - Crystal and Cabochon
stock #20.1-290
Ohngaing, Mogok Valley, Mogok Township, Pyin-Oo-Lwin
Mandalay Division, Myanmar (Burma)
4 x 2.2 x 1.7 CM (miniature)
price: $130


Deep blue hexagonal crystal of Sapphire that is doubly terminated (though more crudely at the bottom) and is complete. A few small bits of Calcite is seen on some faces but this is mostly all Corundum. Included with this specimen is a 1.2 CM cabochon cut from another crystal of the same locality. The pair of Sapphires are somewhat translucent and have some inclusions that add interest. A good cut and rough combo from the famed region of Mogok.

Prehnite
stock #19.1-652
Merelani Hills, Lelatama Mountains, Simanjiro District
Manyara Region, Tanzania
5.9 x 3.7 x 3.4 CM (cabinet)
price: $300


"Cockcomb" habit spray of well defined Prehnite crystals from the recent finds at Merlani. The individual crystals are flattish blade type with distinct individual terminations, up to 2.6 CM tall. The Prehnite is all translucent, has a bright luster and a pleasing green to yellow hue. The white clusters are Calcite (fluorescent) with a few Pyrite cubes scattered about . These Tanzanian Prehnites are a very good value and can have outstanding form. This is a choice example.

Carminite with and in Calcite
stock #18-AX-18-196
La Cigüeña Vein area, Mina Ojuela, Mapimi
Durango, Mexico
7.8 x 6.3 x 2.6 CM (cabinet)
price: $1450


An outstanding Carminite specimen from Ojuela found in the early 80's. Even without the Carminite this would be a fine Calcite with elongated glass clear crystals on contrasting matrix. However as these Calcite are resting on and included by bright red prisms and spays of Micro Carminite it is something very special. The matrix is a complex gossan well covered with micro Carminites which are also on the backside but without the Calcites. Some other very small yellow crystals may be Beudantite but are not analyzed, these are well under .05 MM. The Gemmy Calcite is in excellent condition, with bright luster, The quality of the Carminite (as is typical for the specie) is best appreciated under good magnification, by naked eye it looks like a very red rust, however close exam shows thousands of brilliant red sprays, fans, needles and clusters of Carminites. Choice for the specie and excellent for the locality, Carminite is not often seen larger than thumbnail or micro-mount specimens but this is a cabinet sized specimen with a nice display quality.

Fluorite (phantom) on Muscovite etc.
stock #8.1-077
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
7.3 x 5.6 x 4.8 CM (cabinet)
price: $950


Perfect, with killer color, transparent Fluorite crystals aesthetically perched on a mix of smaller Fluorites and Muscovite. The luster and color zoning are exceptional, there is no damage and the main cubes show penetration twinning. This piece shows very well the quality that made the Yaogangxian Mine's reputation. The cubes have several separate phantoms and a more diffuse core color of vivid purple. An older specimen from 2008, this is quite different from more recent finds and is simply a super piece in person.

Chalcopyrite - coated by Bornite, classic Cornish
stock #1022-JM-4033
Carn Brea Mine, Pool, Carn Brea
Cornwall, England
8.8 x 7.2 x 4.7 CM (cabinet)
price: $360


A choice old Carn Brea (Cornwall) specimen of Chalcopyrite crystals in Tetrahedral form, well coated with a dark Bornite. Excellent pedigree, previous collections include AK Borland, Brian Lloyd and John Marshall (labels etc included). The matrix is mostly Quartz with some pinkish crystals and some areas of Pyrite. The Chalcopyrites are quite sharp, up to 1.4 CM these are protected in two main vugs so most are in quite good condition. Some minor chipping is noted under loupe inspection, overall displays and looks clean. This mine has long ago vanished but over 100 years ago it produced some great Bornite and Chalcopyrite. A nice specimen from a significant locality in Cornwall.
