Microcline - Amazonite crystal
stock #23.1-643
Lake George area, Teller County
Colorado, United States
4.7 x 4.3 x 3.3 CM (miniature)
price: $150

A sharp textbook-form crystal with deep color. Ex Les Hitchings collection, his label notes this was found by Frank Kraus in October of 1982. The color is quite a bit more deep and vivid than is typical. A nice US classic single crystal that is well-terminated and has an incomplete lower termination which is quite uncommon.

Rutile var. Sagenite with Rutilated Quartz
stock #18.1-646
Val Medel (Medel Valley)
Grisons, Switzerland
7.8 x 4.6 x 2.4 CM (cabinet)
price: $450

A fine Alpine classic that is also an antique specimen and quite fine for the locality as well. Older labels are included and the specimen is in very good condition, the Rutile is in crossed clusters of thin crystals in the Sagenite habit. A few small red prisms are also present that are not part of the clusters. The matrix also holds many small Quartz crystals most of which contain lots of Rutile crystals as well. A small affixed label on the backside is the style and type we see in early 19th and later 18th century specimens. We do not know the history of this piece but it is clearly very old and likely dates back over 150 to 200 years. For the Medel Valley this is an unusually fine specimen with individual crystals to 1.3 CM. A great addition for an Alpine or Swiss suite.

Wulfenite, Cerussite, Smithsonite, Mottramite etc.
stock #16.1-680
Tsumeb, Level 30
Otjikoto Region, Namibia
6.2 x 5.6 x 2.6 CM (cabinet)
price: $220

A complex and unusual Tsumeb specimen from the important collection of Cors De Bruin who was employed at Tsumeb starting in 1947. His label gives us the rare detail of locality (30 Level) and has his observation "real mixed-up thing!". The matrix is a heavy mass of Copper/Cuprite that is host to several vugs and zones packed with small crystals and botryoidal masses. The Wulfenites here are mostly the bipyramidal habit. This small specimen is loaded with Copper, Zinc and Lead minerals, the kind of mixing that really only is seen at Tsumeb and one of the reasons it is so revered by collectors.

Heliodor - classic form gem Beryl crystal
stock #16.1-519
Padre Paraiso, Jequitinhonha Valley
Minas Gerais, Brazil
3.2 x 1 x .9 CM (thumbnail)
price: $900

A very fine gem crystal thumbnail. This is a small version of the famed etched Beryls from the golden years of Brazilian pegmatite discoveries. In excellent condition, this has the typical flat termination and all faces have various sorts of geometric etching. The luster ranges from a matte satin to bright glassy in some areas. Nearly 100 percent of the crystal is gem transparent though there are inclusions to note. Ex Les Hitchings collection this was obtained in 1979 on his trip to Brazil. It is not common to find thumbnail sized crystals of this quality.

stock #8.AE-888
Daoping Mine, Gongcheng County, Guilin Prefecture
Guangxi Province, Chile
4.8 x 4 x 3.1 CM (miniature)
price: $330

Apple-green Pyromorphite in fine condition from the classic Daoping mine finds of the early 2000 era. This specimen has 4 different habits of unusual crystallization form present and almost none of the common styles. An excellent specimen for a serious suite of Pyromorphites or for odd habits and rare forms. Elongated spindles, stretched wave forms and others are present. In fine condition, this is nicely attractive on a shelf but amazing and complex when examined closely or with magnification.

Wulfenite with Mimetite
stock #AX-21-044
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
2.8 x 1.8 x 1.7 CM (thumbnail)
price: $700

Wulfenite from the Rowley mine is instantly recognizable, very desirable and regarded as some of the most elegant in the world. This is a choice thumbnail with fine color, form and visual impact. From some angles the form looks like a butterfly with two main crystal wings on matrix. Some small bits of Mimetite contrast as well on the matrix. In exceptional condition, the crystals are the windowpane type and are impressive from all angles.

SOLD Diamond - USA classic from Arkansas
stock #SOLD 21.1-064
Crater of Diamonds State Park, Murfreesboro, Pike County
Arkansas, United States
.25 x .2 x .1 CM (thumbnail)
price: $0

This is the smallest specimen we have ever offered! A nice, complete (though complex and crude) Diamond crystal from the famed Crater of Diamonds in Arkansas. Just .025 carats so this is tiny but fullly transparent and with some interesting inclusions as well. We understand this was found in the late 1960 era. The state park at this locality may be the only fee collecting spot where there is some chance of finding Diamonds though most everyone we know who has tried came up empty handed. A nice locality specimen.

Adamite (Cuprian)
stock #23.1-644
Mina Ojuela, Mapimi
Durango, Mexico
4.9 x 3.4 x 2.9 CM (miniature)
price: $120

Classic Adamite crystals from Mina Ojuela but with the more rare color. Well-defined mint green crystals on contrasting gossan matrix in good condition as seen. The crystals have glassy faces and translucent milky interiors. A nice affordable and attractive Adamite from this most incredibale locality. This can be trimmed to a pair of thumbnails but we like it as is.
