From the famed ancient locale of Fontainebleau this is a choice example of the classic "Sand Calcite". Two complete clusters of these sharp stacked crystals are complete on all sides with no damage. These Calcites are distinctive and are immediately recognizable. Looks fine on all sides.
A fine classic Chessy Malachite replacing Cuprite crystals. The stacked hoppered Octahedral crystals show fine stepped growth, skeletal structure and are quite sharp, fully undamaged on matrix. Attractive on all sides these are compound crystals with the longest crystal edge over 3 CM which is quite huge for this famed location. This type of pseudomorph is on the "short list" of highly desirable classic European minerals and this piece is far better than average. super addition to a suite of pseudomorphs, copper minerals or pseudos.
A perfect complete octahedron of the classic Chessy, French Cuprite form pseudomorphed into Malachite. This is the most iconic habit of this famed locale, and this specimen has the very distinctive hoppered faces that are so unique on these old specimens. No damage and all sides display well, this is a 360 degree piece. An excellent thumbnail with wonderful form.
Outstanding cabinet sized Torbernite with rich green color and incredible crystal form. From the last great finds at Margabal, this is a superb piece in impeccable condition. There are two habits of Torbernite showing two generations on this piece, the largest being the fans of splayed plates. This size and quality is top percentile and the deep forrest green is impressive, but far better in person.
Spangolite with Connellite
La Finosa Mine, Fontana Rossa, Ghisoni Corte, Haute Corse
6.2 x 4.8 x 1.7 CM (cabinet)
A nicely crystallized specimen from this less well known old mine in Corsica. Specimens of this size are very rare and few have crystals that are visible by naked eye. The crystals here are densely packed, cover a sizable area and are brightly colored. The backside is also mineralized but less richly.
Rauenthalite- type locale
Gabe Gottes Mine, Ste-Marie-aux-Mines, Haut Rhin
5.7 x 3.5 x 2.3 CM (small cabinet/ large miniature)
Late Summer 2018
From the type locale at Ste-Marie-Aux-Mines, several areas of white acicular crystals scattered on matrix. Not an esthetic specie (though not really ugly either...), but rare, and an unusually large piece, most specimens are small, often under 1mm. Ex William Hladysz collection.
Transparent blade crystals of Barite with a white fringe and phantoms inside. Sharp and lustrous from a small but remarkable French find 3 years ago. A choice example, very delicate and in eye-perfect condition. With 10 x magnification the main crystals are pristine. At 20 X a tiny chip is found on a tiny side crystal near the base. A choice example.
Cuprite - pseudo Malachite
Chessy Copper Mine, Chessy-les-Mines, Villefranche, Rhone
1.1 x 1 x 1 CM (thumbnail)
Worldwide mix summer
A very sharp complete "floater" cuprite with an uncommon form. This Cuprite is coated with and altering to Malachite from the classic Chessy-les-Mines. Most of these are octahedrons but this is a rhombic-dodecahedron, much like a Garnet shape. No damage, all faces are complete and present. Exam under the microscope shows that there is still considerable cuprite present here this is not a complete pseudo. Choice
