Carminite and Beudantite with Hematite pseudo after Magnetite
stock #19.1-902
Tsumeb
Otjikoto Region, Namibia
5.1 x 4.2 x 3.7 CM (small cabinet/large miniature)
price: $480
Pre Tucson

A serious specimen of Carminite from Tsumeb. This has a super rich zone of free standing Carminite crystals easily seen by naked eye. These show the bright scarlet color that is so distinctive and contrast well. The Carminites are mixed with lustrous Beudantite crystals that look almost black by naked eye but with strong lighting or good magnification they show very well their color. There are three older labels in addition to ours with this specimen; only one (Pequa rare minerals) indicates the source. This is an old piece from prior to 1965 but it is not clear how much older this is. Though the Carminites here are quite visible by naked eye (which is not common) they are amazing under a microscope.

SOLD Turquoise - crystalized classic USA
stock #SOLD 20.1-377
Bishop Copper Prospect, Lynch Station
Virginia, United States
5.1 x 3.3 x 2.7 CM (small cabinet/ large miniature)
price: $0
Pre Tucson

Crystalized Turquoise is quite rare world-wide, the finds of crystal masses at Lynch Station (Virginia, USA) are now classics and found in many collections. This specimen is quite rich, it has two sides of the matrix coated with sparkling green crystals. The size of the crystalized areas and the color are far richer than the average specimens from here. This locality was quite actively collected in the 1960 era but it seems there has not been much or any activity for decades. Well above average and a choice Copper secondary.

Serandite with Behoite - doubly terminated crystal
stock #AX-10-714
Mont Saint-Hilaire, Monteregie
Quebec, Canada
2.6 x 1.5 x .8 CM (thumbnail)
price: $240
Pre Tucson

A salmon pink to orange crystal of Serandite which is complete and doubly terminated. Choice single crystal with fine provenance. This also has a druse of tiny clear Behoite crystals on some faces. Good luster, form and color. From the noted collections of Elmer B. Rowley, William Hladysz and the New York Sate Museum mineral collection with number NYSM 10633. That label is included, the specimen was collected over 60 years ago.

SOLD Microcline - Amazonite crystal
stock #SOLD 23.1-643
Lake George area, Teller County
Colorado, United States
4.7 x 4.3 x 3.3 CM (miniature)
price: $0
Pre Tucson

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.

SOLD Rutile var. Sagenite with Rutilated Quartz
stock #SOLD 18.1-646
Val Medel (Medel Valley)
Grisons, Switzerland
7.8 x 4.6 x 2.4 CM (cabinet)
price: $0
Pre Tucson

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
Pre Tucson

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
Pre Tucson

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.

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

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.
