Herderite - Hydroxylherderite
stock #19.1-341
Conselheiro Pena, Doce Valley
Minas Gerais,
Brazil
3.8 x 2.6 x 2.8 CM (miniature)
price: $220
An older specimen originally labelled as "Herderite" but without analysis it is more likely to be Hydroxylherderite. Either way this is a nicely crystalized Herderite series piece with 3 main crystals in a cluster, the largest being 2.6 CM. The crystals have glassy exteriors, are translucent and with strong backlighting show zoning with a darker orange core and lighter yellow exterior. Some minor contacts but no damage or bruises. Some thin cracks are seen in a few crystal faces these appear to be partly recrystallized under d magnification. There are no repairs, the specimen is solid and stable.
Vesuvianite - Classic locale, complex crystal
stock #AX-22-088
Jeffrey Mine, Asbestos (now Val-des-Sources, Estrie,
Quebec,
Canada
3 x 1.7 x 1.4 CM (small miniature/ large thumbnail (toenail))
price: $360
A vividly colored, complete, doubly terminated crystal (a "floater") with no matrix. From the Jeffrey Mine which is the only locality that ever produced such colorful Vesuvianite. Highly lustrous in person the crystal has is mostly a mix of green hues from dark to lighter yellowish and has one spot of purple. In fine condition, the faces on this are multi stepped and quite a bit more complex than most crystals from this famed locale. The mine has been closed for years but the heritage of its minerals is world renowned. Choice

Kalliosalo, Nurmo, Seinäjoki
South Ostrobothnia,
Finland
3.7 x 3.1 x 1.7 CM (miniature)
price: $220
A lustrous metallic mass of Antimony that shows complex cleavage structures and somewhat crude crystal faces. From Kalliosal in Finland this seems to be a very pure sample and hefty at 48 grams.
Azurite, Malachite etc
stock #20.1-280
Touissit, Touissit-Bou Beker Dist., Jerada Province
Meknes-Tafilalet Region,
6.2 x 4.4 x 2.7 CM (cabinet)
price: $430
Brilliant Azurite crystals up to 2.5 CM on a mixed matrix of Dolomite and Malachite. The Azurites are sharp, flat habit with steep tapering terminations some being very pure, gemmy transparent while others are partly altered to Malachite and are opaque. In fine undamaged condition, from the great finds at Touissit in the 1970's, this displays well and is nicer in person too.
A rarely seen native element, Mercury sometimes is found in oxidized parts of Cinnabar deposits. This is an incredibly rich piece with dozens of globules partly protruding from the matrix, The silvery globs are in some cases over 2-3 mm and very dense so easily seen on display, not like most pieces which are rather subtle. As is the case with all such specimens it has been sprayed with a non visible fixative to keep the droplets from shedding. There are a few tiny spots of silvery metallic Tiemannite which is a rare Mercury Selenide. The matrix is a shale with a few zones of bright red Cinnabar. Choice and not often available, this is a 1960's vintage specimen, the original label only gives the county as a locale but this looks like a perfect match for specimens from the Socrates Mine.
Anglesite in Sulphur
stock #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.

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.
