Group of very sharp and tabular wulfenite crystals, with an excellent brilliance, color varies between orange to red and from translucent to transparent. They are disposed very aerial on a matrix of goethite. Main crystallographic forms we can be observe are the first and second order tetragonal pyramids, truncated by the pinacoidal faces. These specimens often have some crystals with small breaks, in this sample there is only a small fractured crystal, not visible. It is one of the most complete and damage free specimen I found.

Size: 4.0 x 2.5 x. 2.0 cm.
Main crystal: 7 x 7 mm.

A rarely seen hematite "iron rose" very gemmy, sharp and thick, good size, with smoky transparent quartz crystals. The hematite rose is very lustrous, and aethetically disposed on the quartz matrix and with the classic silvery metallic color. From a Chinese locality from not many specimens have been yield.

Size: 8.3 x 6.4 x 3.4 cm.
Main crystal: 34 x 15 mm.

Group of interpenetrated cubic fluorite crystals, brilliant and very transparent, with a delicate green color. Well defined faces and beveled edges by the dodecahedron. A brilliant specimen.

Size: 6.0 x 5.5 x 4.7 cm.
Main crystal: 35 x 34 mm.

Druse of fluorite crystals with a marked color zoning. An intense violet crystal core and colorless in the edges, with some geometrical zoning on some edges. An interesting fluorite specimen. Accompanied by lenticular crystals of siderite. Very aesthetic.

 

Size: 12.3 x 9.0 x 3.8 cm.
Main crystal: 7 x 7 mm.

These specimens, novelty, 2014, show very unusual fluorite crystals, with an uncommon color. They show cubic crystals beveled by the dodecahedron and deep hoppered growths. Also almost globular crystals in which the dodecahedral forms predominate. The color is very, very intense, vivid shades that vary between indigo and navy blue, clearly visible when light is incident. We observed also green tones within a few crystals. They have grown on quartz crystals covered by layers of smaller milky quartz. An aesthetic specimen for fluorite and crystal collectors.

Group of very sharp calcite crystals, two of them predominant, those show very developed prism faces mixed with the positive rhombohedron faces. Regarding the upper terminal faces we can observe the negative rhombohedron with striations. This type of crystallization is very unusual, I have not seen this combination, with this quality, never before. It presents some transparence and a more remarkable brilliance. It is accompanied by other calcite crystals of the same habitus, with a developed prism. A seldom seen piece for this mine. A sample for the best calcite collector display.

Size: 10,7 x 10,4 x 9,5 cm.
Main crystal: 8,0 x 3,5 cm.

Fluorescent under long wave UV

A perfectly balanced specimen. On the one hand we have a large scalenohedral crystal (5.2 x 2.3 cm.) showing perfectly defined the 180° twin between two scalenohedrons. This crystal is very defined and "doubly terminated" shows good transparency and brilliance. On the other hand we have a group of calcite crystals, also scalenohedral, interpenetrating each other, brilliant and translucent, with a slight yellowish tone. They are disposed on a matrix of tiny quartz crystals on which observe small aggregates of cubic violet fluorite, also interpenetrated. A specimen to be displayed.

Fluorescent under long wave UV

This elegant specimen presents a cube-octahedral fluorite crystal, with well defined faces and curved edges and good size. Color from green to blue, with some zoning. It is very aerial disposed on a white quartz matrix, with pyrite in the back side, and it is accompanied, to increase its aesthetics, by a rich group of calcite crystals, with a curious banded brown tones. An unusual specimen, with an incomparable presence.

Fluorescent under long wave UV

A very rich group of sharp psedo-octahedrical scheelite crystals, with an intense brown color, excellent luster and some transparence. They are disposed on a quartz matrix partially covered by small clinochlore green crystals. A very nice specimen for display.

Fluorescent under short wave UV

On a matrix formed by corroded quartz crystals, due to chemically aggressive media, are disposed several small pyromorphite crystals of hexagonal prismatic habit, with a extraordinary brilliance, transparence and definition. In addition, its color, almost yellow-green near fluorescent, adds a special touch to this sample. The Daoping Mine has produced a large variety of pyromorphite since ca. 2000 and this is a particular example.

Thin needle like Carbonate-cyanotrichite crystals disposed as a velvet layer and as radial aggregates on a matrix with cubic colorless Fluorite crystals. These aggregates show a intense blue sky color, deep in the core.
