Anglesite in Sulphur
stock #19-AX-9-051
Ahumada Mine, Los Lamentos
Chihuahua, Mexico
5.6 x 3.2 x 2.2 CM (small cabinet/ large miniature)
price: $90


An oddity, from Los Lamentos, the locality world famed for superb Wulfenites, this is a different association. The mine contained a large amount of Sulfate minerals along with the Lead secondary species and some Native Sulphur. This Sulphur mass has both massive and micro crystal areas and is the matrix enclosing several Anglesite crystals about 1 CM in size. Not often seen for sale, this piece dates from the 1970's.
Copper -superb spinel twins
stock #14.1-407
Central Mine, Keweenaw Co.
Michigan, United States
7.4 x 4.1 x 3.4 CM (cabinet)
price: $1200


Simply fantastic, a very well crystallized Copper with sculptural form much like a tree or cactus. The most prominent twin crystal at the top is 3.1 CM tall and the whole is very esthetic. From the Central mine of Michigan, this classic site produced many excellent spinel twins in its working life. This is well above the quality of "typical" pieces which are now uncommon. A fine USA classic copper that would be desirable from anyplace, a super example of the fames Upper Peninsula copper country. The piece displays great from almost any angle.
Chalcedony / Amethyst
stock #20.1-277
Mamuju area, Sulawesi Barat province
Sulawesi Island, Indonesia
3 x 2.2 x 1.7 CM ()
price: $120


Highly esthetic and in fine condition from the incredible find at Mamuju, Sulawesi (Indonesia). This important discovery yielded some large and impressive pieces, but very fine thumbnails like this were much less common. This is a colorful and high impact small piece that is an elegant sculpture. From one of the best modern mineral discoveries.
Chalcedony/ Amethyst
stock #20.1-278
Mamuju area, Sulawesi Barat province
Sulawesi Island, Indonesia
3.3 x 2.4 x 2 CM (small miniature/ large thumbnail (toenail))
price: $90


Esthetic and withy nice form from the incredible find at Mamuju, Sulawesi (Indonesia). The less common green balls mixed with purples makes a nice contrast. This important discovery yielded some large and impressive pieces, but good thumbnails like this were much less common. This is a colorful and high impact small piece that is an elegant sculpture. From one of the best modern mineral discoveries.
SOLD Andalusite (var.Chiastolite) -crystal section
stock #SOLD 15.1-600
Brockelman Road, Lancaster, Worcester County
Massachusetts, United States
2.2 x 2.1 x .5 CM (thumbnail)
price: $0


An unusually sharp and super distinct old Chiastolite (Andalusite) crystal cross section. From the classic Lancaster Massachusetts locality this was collected in 1938 by Harvey Owens, ex Warren Johansson collection. Sawn on both sides but not polished, the pattern is textbook perfect, clear and distinct on this slice. An older US classic piece not like more recent finds.
Tennantite
stock #13.1-238
Tsumeb
Otjikoto Region, Namibia
2.6 x 2 x 1.2 CM (thumbnail)
price: $190


A cluster of very sharp Tennantite crystals with no matrix. The patina on this thumbnail is a sooty dark metallic which is typical for Tsumeb. Displays well from several angles, the Tetrahedral form crystals form a sculptural grouping that shows the textbook perfect form well.
Barite with Fluorite (US classic)
stock #0307-JM-1632
Cave-in-Rock, Hardin County
Illinois, United States
7.9 x 5.8 x 3.7 CM (cabinet)
price: $1150


An outstanding classic that is rarely seen on the market. Sheaves of fine blue Barite crystals in radiating habit on a contrasting Calcite matrix. Fluorites are noted on the edge and backside, but the main impact is from the Barite. Ex John Marshall collection, this has the rare strong blue color, most Barites were a cream white to gray hue. In very good condition as seen, the piece is very three dimensional with top color and form. A fine addition to any good suite of southern Illinois minerals, US classics or Barites.
Topaz- gem clear crystal on matrix
stock #20.1-271
Sakangyi-Kyauk-Pyat-That, Mogok, Pyin-Oo-Lwin,
Mandalay Division, Myanmar (Burma)
4.3 x 3 x 2.1 CM (miniature)
price: $380


Water clear Topaz with perfect form perched on a jagged pegmatite matrix. From the Sakangyi Mine which produced much fine Topaz at one time, this locality has been idle for a few years but is likely not fully exhausted. Very glassy luster, a few faces show extra modifications but overall a classic textbook crystal form. Quite a lot of Sakangyi Topaz had frosted faces and distinct striations, but some smaller crystals like this have faces with no visible striations but have a few termination faces showing a bubbly texture. All in all a pretty prism. No damage.
