An excellent double terminated group of two quartz crystals, overgrought by well developed chalcopyrite followed by sphalerite and second generation quartz.
Fragment of transparent sphalerite-cleophane crystal. Color is spread in the stone, from red to orange and to yellow-green. Stone is convenient for faceting. Pictures are taken in transmitted (Backlight).
An excellent specimen presenting a cluster of long axis amethyst crystals with the phantom spreading of color and small sphalerite crystals on one side of the crystals
An extraordinary cabinet size specimen of space developed quartz with galena, sphalerite, and chalcopyrite, secondary oxidized to bornite and covellite
A very nice and aesthetic specimen of Longaxes needle quartz overgrought sphalerite, galena, and sphalerite. There are light oxidation signs on pyrite as result of coating by bornite.
A very aesthetic cluster of clean long axes amethyst crystals with the zonal spreading of color developed on the base of galena and sphalerite.
A nice specimen of galena, covered with small galena and sphalerite crystals, followed by larger galena crystals with very well terminated shiny galena crystals twined in Spinel law twins in some places
A completely transparent fragment of cleophane crystal with zonal distribution of color. Main part is in yellow-greeen to green color, but in the part of the stone thereis orange to yellow-orange color. Pictures are taken in transmitted (backlight). The specimen is convenient for faceting.
One of the last pieces of our famous cavity of intensive green (emerald color) cleophane. Pictures are taken in transmitted (backlight). The specimen is convenient for faceting.
An excellent cabinet size specimen of small shiny crystals of galena, very bright black tetrahedron sphalerite – marmatite, quartz and thin pseudo-hexagonal flat calcite crystals with priority developed basal pinacoid.
