Rutile on Hematite - epitaxial twins
stock #20.1-713
Novo Horizonte
Bahia, Brazil
3.2 x 2.4 x 2.1 CM (small miniature/ large thumbnail (toenail))
price: $190


Intergrown stars of golden Rutile needles radiating from Hematite crystals. A classic of mineralogy, the six rayed stars oriented on flat Hematite crystals shows the twinning and epitaxy perfectly. Delicate but elegantly composed, these are one of the most amazing of Brazilian minerals. This is a choice three dimensional piece that looks fine from any angle.

Brewsterite - classic, type locality
stock #20.1-714
Bellsgrove Mine, Strontian
Northwest Highlands, Scotland
8.9 x 6.3 x 3.5 CM (cabinet)
price: $280


A sizable and very fine cabinet specimen of well-crystallized Brewsterite from the type area for the specie. Brewsterite is the less common analogue of Heulandite and can be Sr or Ba dominant. This specimen is almost certainly the Sr dominant version though not tested. This has hundreds of well-formed crystals which are transparent to translucent and very lustrous. Ex Hitchings collection this is an older specimen that was obtained in trade. Excellent undamaged condition.

Calcite on Conichalcite and Malachite
stock #20.1-712
Mina Ojuela, Mapimi
Durango, Mexico
4.7 x 2.8 x 2.6 CM (miniature)
price: $120


A cute and colorful miniature from the great Mina Ojuela. Transparent Calcites are included by a fibrous Malachite and sit on a mixture of botryoidal Conichalcite and Malachite. This could be trimmed to a thumbnail size but this is very nice as is. In fine condition as seen, this is a very good example of an esthetic but affordable specimen, carefully selected from amongst a huge number of average level specimens.

Scorodite - classic Mexican
stock #10.1-330
Mina Ojuela, Mapimi
Durango, Mexico
6.7 x 5.8 x 4.8 CM (cabinet)
price: $450


A hefty cabinet-sized Scorodite specimen with very lustrous crystals from the earlier find at Mina Ojuela. At first glance the Scorodites look dark almost black but under strong lighting they are a dark transparent blue with a few green and yellow-green crystals mixed in. Unlike many Scorodites from Ojuela this does not have a crumbly matrix, this is a solid piece with no hint of degeneration. An excellent value, this piece from the earlier find in the 1970's is very different from the 2015-16 find, and these are rare on the market.

Adamite - purple
stock #17.1-548
Mina Ojuela, Mapimi
Durango, Mexico
4.4 x 3.7 x 3 CM (miniature)
price: $240


A pretty yet affordable miniature of the rarest color of Adamite, a good deep magenta-purple. Ex Les Hitchings collection, this has larger crystals with purple to white zoning and smaller crystals with a more vivid purple. As is typical of these Adamites the color is more concentrated and vivid at the terminations. The matrix holds a bonus some micro slender Legrandite crystals on the backside in a small vug of the Goethite matrix.

Mimetite
stock #20.1-711
Mina Ojuela, Mapimi
Durango, Mexico
3.6 x 2.2 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $70


A cute, smaller old style Mimetite that looks like a yellow-orange brocolli perched on a sliver of matrix. Good wet luster and sparkle. 1970's era specimen that could be trimmed to a thumbnail but looks fine as is. Good value for a cute Mimetite.

Euchroite - well-crystallized, type locality
stock #17.1-715
Lubietova, Slovenske Rudohorie Mts,
Banska Bystrica Region, Slovakia
1.6 x 1.5 x .8 CM (thumbnail)
price: $300


Super crystals of the rare Copper Arsenate Euchorite from the type locality. The color and form are especially nice on this thumbnail, there is a slight translucence and classic waxy luster. Examination with good magnification finds a few tiny rough spots and the backside is incomplete, but by naked eye the condition is excellent. Though not perfect the quality for this rare specie is still very fine and not often available. A slightly bent or curved aspect to some faces is noted as was often the case in the larger crystals in the type locality. These crystals are very large for the locality and for the specie. An older specimen, Ex Rejl collection.

SOLD Fluorite - USA Classic
stock #SOLD 18-AX-20-222
William Wise Mine
New Hampshire, United States
6.6 x 4.8 x 4.8 CM (cabinet)
price: $0


A rich deep green frosted octahedral Fluorite crystal from the Wise Mine (New Hampshire, USA). This is one of the oldest Fluorite mines in the Americas and a classic locality known for this unique green color, since the 1870's, mined commercially since the 1890 and closed by 1919. Wise Fluorites are immediately recognizable, the form, luster and color set these apart. This is far better than typical, there are some edge modification faces and a sprinkle of Quartz that adds sparkle. Aside from the area where this was removed (the base is contacted as seen) the condition is very good and excellent for this famed old locale.
