Mixite - historic specimen
stock #AX-35-144
Mammoth Mine, Tintic Mountains, Juab County
Utah, United States
7.6 x 4.5 x 2.7 CM (cabinet)
price: $320


This specimen dates to the famed Levison collection (New York City) acquired in 1899. Mixite is considered fairly rare, an unusual Bismuth Copper Arsenate, almost never seen in display specimens. This is a sizable and complex multi-specie piece with a Barite matrix hosting areas of Mixite, Malachite plus what seems to be Olivenite. There are a few additional small crystals not identified. The Mammoth area of Tintic was a fantastic locality that provided some rare and exotic species including five new minerals. This specimen has a very tattered old label affixed (not easy to read) and we also include a photocopy of the page from his collection ledger for this piece. A nice example in a sizable specimen.

Gyrolite on Prehnite with Quartz
stock #20.1-614
Mumbai District
Maharashtra, India
1.8 x 1.5 x 1.2 CM (thumbnail)
price: $110


Esthetic small thumbnail that is centered on the spherical arrangement of tiny Prehnite crystals. The ball shows the lathlike crystals well and hosts smaller balls of white Gyrolite. The matrix is crystallized Quartz and is an unusual older specimen for the Decan plateau of India. Ex Larry White collection, he obtained this from Dudley Blauwet (Mountain Minerals) in 1990. The locality information at that time was simply Bombay, India which was the standard locality given at that time for most Indian Zeolites. This is however now called Mumbai, it is in in Maharashtra, our Indian sources say it is from the only find ever with associations and form like this. A sweet thumbnail that is certainly not typical from India.

SOLD Fluorite on Quartz
stock #SOLD 18-AX-20-239
Redstone Quarry, Conway, Carroll County
New Hampshire, United States
8.3 x 3.2 x 2.9 CM (cabinet)
price: $0


A very unusual New Hampshire (USA) Fluorite from the Redstone Quarry. The Fluorites are clustered in semi-spherical groups perched on clear Quartz crystals. The Fluorites themselves are sharp, transparent green perfect small cubes with dark purple zoning in the corners and some edges. No damage, an older specimen pre 1970 from the collection of Les Hitchings. Most of the Fluorites from this area are frosted or etched, I have only ever seen two of this habit. A nice New England pegmatite specimen that is really different.

Smithsonite
stock #20.1-615
Tsumeb
Otjikoto Region, Namibia
2.4 x 1.7 x 1 CM (thumbnail)
price: $240


Translucent to transparent Smithsonite crystals on a gossan matrix. Very sharp and perfect form, these scalenohedral prisms are nicely perched and have tiny deposits of Hematite adding color. The orange-red crystals can look a bit like Rhodochrosite at first glance, but this is color from Iron, not Manganese. Attractive and choice thumbnail from the amazing deposits at Tsumeb.

Smithsonite
stock #16.1-202
Tsumeb
Otjikoto Region, Namibia
2.5 x 1.8 x 1.3 CM (thumbnail)
price: $140


Sharp scalenohedral crystals of Smithsonite with a pale yellow color perched on a Sulphide matrix. Tsumeb Smithsonites were found in every color and form possible, this is a choice thumbnail in fine condition as seen.

Aquamarine - tapered termination, etched crystal
stock #AX-7-058-(162)
Medina Pegmatite field, Pedra Azul District
Minas Gerais, Brazil
5.1 x .5 x .4 CM (small cabinet/ large miniature)
price: $180


A "needle" of sharp gem-clear Beryl in perfect condition. The sides are etched along the "C" axis and the termination is the uncommon pointed, tapered type. Ex Larry White collection; this dates to the late 70's early 80's vintage.

Beryl var. Aquamarine with Schorl
stock #20.1-612
Hohenstein Massif, Omaruru District
Erongo Region, Namibia
2.3 x 1.3 x .9 CM (thumbnail)
price: $110


Fine blue color and gem transparency on this Erongo thumbnail of Aquamarine. Nice contrast with the black Schorl crystals that are the only matrix. The Beryl is very sharp, complete and undamaged. This find of Aquamarine about three years ago was quite large. We selected a small number of the most perfect small pieces from that large lot. This has above average color and quality.

Agate - replacing fossil gastropod
stock #16.1-366
Erfoud, Er Rachidia Province
Meknes-Tafilalet Region, Morocco
4.6 x 1.8 x 1.5 CM (miniature)
price: $80


A complete and perfect fossil Gastropod that is fully and sharply replaced by Agate. This Silicate replacement has preserved all the details of the shell except for the internal opening, this is no longer hollow as it is solid Agate. Even for those of us who are not collectors of fossils, this form of Quartz is really attractive.
