Chrysoberyl - twinned crystals
stock #20.1-815
Colatina
Espirito Santo, Brazil
2.3 x 1.5 x 1.3 CM (thumbnail)
price: $380
new year 2021

Fine thumbnail of Brazilian Chrysoberyl. A crystal cluster vintage 1948 with a dated but badly tattered Shortmann's Minerals label included that puts this piece at the very beginning of Brazilian specimens being exported. Good glassy luster, translucent to gemmy transparent areas and nice green-yellow color with classic twinned forms. Some reddish inclusions are seen that add a little contrast but no matrix, a floater this is complete all around. The original label is spelled Collentina which is not correct but this misspelling was used by both Arthur Montgomery and Alan Kaplan at that time. Either person could have been the source of this piece.

Tennantite and Siderite - classic European
stock #17.1-032
Barbora Adit, Knottei area, Krupka, Krusne Hory Mts
Usti nad Labem Region (Bohemia), Czech Republic
5.4 x 3.3 x 2.2 CM (small cabinet/ large miniature)
price: $150
new year 2021

A very old and very rich Czech Tennantite from this historic mining region. The matrix is a sparkling Quartz with several large (for the locality) Siderite rhombs up to 2.5 CM. The Tennantites are in clusters of many small, distinctive crystals, up to 4mm - though most are smaller. The Tennantite masses are relatively bright, lustrous and includes many twins. A small amount of Chalcopyrite is seen with magnification. This can be displayed from several angles that show more Dolomite or more Tennantite depending on preference.

SOLD Wulfenite with Mimetite
stock #SOLD 17.1-166
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
2.1 x 1.6 x 1.4 CM (thumbnail)
price: $0
new year 2021

A superb and perfect thumbnail of bright orange windowpane Wulfenites with a scattering of red Mimetite. The Wulfenites are perched like wings on a small mound of solid matrix so this looks like a butterfly from some angles. Even under strong magnification this is flawless, undamaged and looks fine from any angle. The Rowley Mine is one of the great USA localities for Wulfenites, the crystals tend to be small, thin and brilliant. The mine, before it closed in recent years, was an excellent source of specimens but fully perfect competition quality was very rare. We have handled many good pieces and are currently offering some others on line, but this is simply not a typical level piece. Far better in person and an outstanding colorful, delicate Wulfenite that is a choice example of this iconic locality.

Fluorite on Muscovite with Quartz
stock #6.2-568
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
10.4 x 6.4 x 5.8 CM (cabinet)
price: $880
new year 2021

A choice old Yaogangxian specimen with fantastic contrast. Purple phantom Fluorites in a cluster set like jewels on matrix, the largest crystal about 2.5 CM diameter. Transparent to translucent Fluorites with a glassy to waxy luster, these look fine from just about any angle. In fine condition overall, by naked eye there is no visible damage, just some minor rough spots. With a good loupe some small bruises are seen, this is not distracting and is lost in the bigger context. The color ranges from the "grape purple" phantoms to a lighter violet-blue in the crystal bodies, glows great if backlit. This is 2006 vintage, from the "golden years" for Fluorites at Yaogangxian.

Dolomite - iridescent
stock #20.1-814
Tsumeb
Otjikoto Region, Namibia
3 x 2.4 x 2.3 CM (small miniature/ large thumbnail (toenail))
price: $120
new year 2021

An unusual and attractive thumbnail of Dolomite crystals from Tsumeb with iridescent sheen. An older piece originally labelled "Cobaltoan Dolomite, Tsumeb SWA", however, this does not look at all like the usual Cobalt coloring and doubt the accuracy of that. This is however unusual looking for Tsumeb the crystals are sharp, slightly curved and have reddish-purple highlights.

SOLD Tephorite - crystalized with Willemite etc.
stock #SOLD 20.1-640
Franklin Mine, Franklin Mining District, Sussex County
New Jersey, United States
3.4 x 2.6 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $0
new year 2021

A Franklin, New Jersey classic, a mass of Tephorite crystals with green Willemite crystals and some small areas of what seems to be Hodgkinsonite and Friedelite. This is an old specimen that was for many years in several European collections, those labels are included. Tephroite in massive form is not very rare at Franklin, but the tiny, sharp and gemmy crystals are quite rare and not often available.

Vanadinite
stock #13.1-224
Mibladen Mine, Upper Moulouya lead district, Midelt, Khenifra Province
Meknes-Tafilalet Region, Morocco
4 x 2.4 x 2.7 CM (miniature)
price: $140
new year 2021

Vanadinite crystals with both brilliantly lustrous red faces and some faces that are a mustard color. The form and esthetics are choice and looks fine from several angles. Vanadinite from Morocco has been rather plentiful for the past few years and the costs are still reasonable for such an attractive specie.

Apatite, Siderite, Quartz and Pyrite
stock #17.1-054
Panasquieira Mines, Panasquiera Covilha
Castelo Branco District, Portugal
11.1 x 8.3 x 4.2 CM (cabinet)
price: $390
new year 2021

A complex mix of sharp gemmy Apatites with Quartz crystals that are in turn covered with small Siderites and a sprinkle of Pyrite. From the famed Panasqueira Mine, this is both esthetic and has an unusual presentation. The Apatite (Fluorapatite) is vividly fluorescent and in fine condition.
