Copper in Calcite with Epidote, Microcline and Pumpellyite
stock #21.1-322
Houghton County
Michigan, United States
4.8 x 4 x 4.1 CM (miniature)
price: $170
Late Summer 2021

Some masses of native copper mixed with gem clear Calcite crystals, most of which are richly included. A complex specimen on an amygdaloidal basalt matrix having many cavities filled with micro crystals. These vugs hold many Epidote crystal clusters most being on contrasting salmon colored crystals of Microcline. Good looking by naked eye but really amazing with magnification, this has a good mixture of species and is classic upper Michigan material. Unfortunately we have no mine attribution but this looks like a perfect match to the famed Quincy Mine.

Fluorite - USA classic, vintage 1950
stock #21.1-326
Cave-in-Rock, Hardin County
Illinois, United States
4.4 x 3.3 x 2.5 CM (miniature)
price: $280
Late Summer 2021

A nearly pure bright yellow color Fluorite with a tiny faint zone of light blue on some edges. This is an old piece with a tattered label dated 1950. The color and translucency is excellent, there are some edges that are slightly rough, the back and one side are the point of removal. The display side of the two main cubes is in nice condition. There is one round "Barite hole" on a face that adds a nice accent. Close exam of the wider faces shows many geometric growth structures and a little stepping, the luster is wet looking.

Variscite half nodule with Crandallite and Wardite
stock #21.1-330
Little Green Monster Mine, Clay Canyon
Utah, United States
7 x 5.5 x 3.2 CM (cabinet)
price: $450
Late Summer 2021

A complete half nodule of colorful phosphate minerals from this famed, classic US locality. The nodule has a full mineralized edge rim in perfect condition with no chipping or missing bits which is most desired. The color zoning of the bright yellow to greenish Crandallite is especially distinct on this specimen, it has a clear separation line and contrasts well with the inner white and green interior. This piece is from the early excavations at this site by the legendary team of Over and Montgomery. Choice and better in person.

Roselite - well-crystallized
stock #21.1-321
Aghbar Mine, Aghbar, Agdz Cercle, Zagora Province
Draa-Tafilalet Region, Morocco
6.2 x 3.2 x 3.2 CM (small cabinet/ large miniature)
price: $290
Late Summer 2021

Vivid deep color and highly lustrous, these crystals of Roselite contrast with the Dolomite matrix. The finds at the Aghbar Mine of Roselite, and several other fine Cobalt minerals, are considered to have been the best for these species in the world. The crystals here are translucent to transparent, densely deposited in a protected vug 4.6 CM across.

Adamite on Gossan (Hematite)
stock #AX-19-062
Mina Ojuela, Mapimi
Durango, Mexico
7.6 x 4.7 x 2.3 CM (cabinet)
price: $120
Late Summer 2021

Adamite crystals in pale green balls scattered on a contrasting red Gossan matrix. In fine condition as seen, the balls are in clusters and a few are fully isolated. Good sparkling luster in the spheres and with nicely fluorescent as well. Adamites from Ojuela are incredibly varied in color and habit, some forms do not exist in any other locality world wide. Modern classics this is an affordable yet very pretty specie and specimen.

Beryl var. Aquamarine with Albite, Muscovite
stock #6.2-639
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan Province, China
5.6 x 4.2 x 3.3 CM (small cabinet/ large miniature)
price: $320
Late Summer 2021

A modern classic, an early Xuebaoding type Beryl from Pingwu vintage 2004 season. The Beryl is very glassy the broad faces of the tabular crystal have complex geometric facets from both etching and multiple recrystallizations. The outer narrow faces are sharp and glass-like. Just one narrow edge has some damage not visible from most logical viewing angles but overall the condition is outstanding. The most prominent Albite crystal is a blocky type with pearly luster making a nice contrast. This form of tabular Aquamarine Beryl is rare worldwide but this high elevation locale has almost all of its Beryl in this form.

Wulfenite with minor Mimetite
stock #A-21-048
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
5.3 x 3.4 x 1.6 CM (small cabinet/ large miniature)
price: $1650
Late Summer 2021

Delicate and fine windowpane crystals of Wulfenite stand up from the matrix in a complex array. Very sharp, intense color and with glassy luster, the Wulfenites are all fully transparent. A few tiny balls of Mimetite are present but they are minor in comparison to the Wulfenite. In incredible condition which is amazing given the fragility of the crystals. From the final specimen recovery operations at the Rowley. This can be shipped safely (not recommended however for international orders). If requested we can hand deliver at a major mineral show. Much better in person, the bright luster is hard to fully appreciate on a computer screen.

Strontianite on Barite
stock #21.1-312
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
10.6 x 7.7 x 5.3 CM (cabinet)
price: $750
Late Summer 2021

Superb combination specimen of Strontianite crystal ball-clusters on contrasting Barite blades. A classic southern Illinois specimen that is far more esthetic than typical for these species. The famed Fluorites from this mine tend to overshadow the excellent (and more rare) Strontianites. In perfect, undamaged condition, the Barites are in two generations and have a pale blue hue while the Strontianites in "puffball" form are a pale yellow creme color. In person the luster and sparkle are especially impressive. Strontianite is not usually a very attractive mineral but is respected especially from the classic localities on Europe, but not often an attractive specie. This specimen that is as fine as can be found from the USA and far more attractive than usual.
