Fluorite Octahedral with Chalcopyrite and Quartz
stock #18.1-141
Malmberget, Gallivare
Lappland, Sweden
6.9 x 5.3 x 4.2 (cabinet)
price: $440
Spring update

Sharp Fluorites from the classic Malmberget locality, famed for butterfly twin Calcites. Less famed but still excellent are the Fluorites and Stilbites from here. An excellent example in very good condition as seen with several mint green octahedral crystals. The main Quartz is about 2 CM tall and well decorated by bright Chalcopyrites, adding a nice contrast and luster. No damage seen by naked eye, some tiny chips can be found with 20X magnification, so very close but not quite perfect. A modern classic locale, these FLUORITES ARE NOT OFTEN AVAILABLE
Hydroxlherderite- large, fine crystal
stock #16.1-463-CN3010
Linopolis, Divino das Laranjeiras, Doce Valley
Minas Gerais, Brazil
8.3 x 6.4 x 4.3 CM (cabinet)
price: $1500
Spring update

A superb large euhedral crystal (7.8 CM tall) dominates a cluster of smaller crystals. Sharp, complete all around and undamaged, this is an incredible example from the famous Linopolis find thirty years ago. Micro crystals of some unidentified Phosphates are also scattered on the specimen and add a little sparkle. Ex Charles Noll collection, the original label call this Herderite as these wwere known then, now understood to be Hydroxlherderite. Most faces show a glassy luster and are transparent in parts. The color of Hydroxylherderite from here can vary widely, this one is mostly light violet-purple but with some zones of greenish, grey and orange. Display well from all sides and the main crystal is textbook quality. These only appear now from old collections like this.
Semseyite- large crystals with Sphalerite, Sphaerosiderite etc
stock #18-AX-18-197
Herja Mine, Chiuzbala , Baia Mare
Maramures, Romania
9.1 x 7.8 x 4.5 CM (cabinet)
price: $500
Spring update

Very well formed, large (to 4 CM across) rosettes of sharp and lustrous Semseyite in undamaged condition. The matrix is a mix of lustrous black Sphalerites and Sphaerosiderite balls colored by Boulangerite. A few Chalcopyrites sprinkled in add a little extra color. These are the biggest undamaged osettes we have handled, the overall esthetics is very strong and fine for the specie.
Cuprite -Large complex crystal on Malachite
stock #0739-JM-1693
Dikuluwe Mine, Kolwezi
Shaba, Democratic Republic of Congo (Zaire)
7 x 6.6 x 3.8 CM (cabinet)
price: $880
Spring update

A large, somewhat crude red Cuprite octahedron (3.5 CM) with some unusual growth features and complex faces sets nicely on Malachite matrix. Two of the faces have odd holes (one circular, one triangular) and several parts of the crystal show stepped regrowths. Great color contrast, with backlighting the Cuprite glows a brilliant cherry red. We have not backlit the specimen as that can be misleading, but the cuprite is fully translucent and seems to be facet grade clear red inside. Ex John Marshall collection (his label and card are included) acquired in 1990 from G. Gauthier.
Quartz on Chrysocolla Pseudomorphs
stock #18.1-130
Inca De Oro, Chanaral
Atacama Region, Chile
9.1 x 6.8 x 5.2 CM (cabinet)
price: $800
Spring update

Brilliant sparkling blue Chrysocolla overgrown by gem clear druzy Quartz. The Chrysocolla has replaced earlier acicular crystals of an unknown mineral possibly the rare acicular form of Dioptase. The individual needles reach 1.5 CM A single broken needle off to the side seems to show a core of Dioptase but this is not confirmed. No matter what the original material this is very esthetic and totally different from any other Chrysocolla. An attractive, intriguing and unique Copper specimen!
Fluorite- gem clear tabular habit
stock #18.1- 140
Cantera Llamas, Duyos, Caravia
Asturias, Spain
3.7 x 2.7 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $290
Spring update

A super toenail sized Fluorite with a very fine flattened cube form and top clarity. From the small but important Llamas Quarry in Northern Spain, this is in pristine condition. The matrix is a mass of small crystals of Fluorite all showing the elongations and beveled edges that are classic for this area. Choice.
Adamite- gemmy crystals on gossan
stock #18.1-139
Mina Ojuela, Mapimi
Durango, Mexico
7.8 x 5.8 x 4.8 CM (cabinet)
price: $330
Spring update

A pretty and unusual Adamite from 1960 vintage finds at Mina Ojuela. There are two generations of well crystallized Adamite on matrix, the first is a light green to lemon yellow chisel-tipped type, the second is colorless to white. Bright and vividly sparkling in person, the luster and quality are impressive. More recent specimens have a very different look. Very strong fluorescence as well, this has far better esthetics than typical Mexican Adamite.
Andalusite - Chiastolite (fairy cross)
stock #12.1-AX-164
Rutongo area
Kigali, Rwanda
5.2 x 4.2 x 3 CM (miniature)
price: $80
Spring update

A sizable Chiastolite crystal with a distinct Fairy cross from an uncommon locale, Rwanda. One face has been ground to show the structure with the back and sides left fully natural. This is the only example I have ever seen from there, this is from a 1970s vintage collection.
