One extraordinary cabinet size specimen of plated galena crystals with skeletal development in some parts developed on quartz and followed by chalcopyrite and black sphalerite – marmatite
One exceptional and very aesthetic cabinet size specimen of small cubic and very lustrous galena and pyrite crystals, covered by very thin clear small quartz crystals, very interesting arranged in the space, forming the starts like groups of crystals.
An excellent cabinet size specimen of small galena and sphalerite crystals, overgrowth by very lustrous pyrite crystals lately, in the process of oxidation, coated by bornite and covellite.
An excellent, large cabinet size specimen of quartz overgrowth by sphalerite, galena and followed by very well shaped chalcopyrite. Galena is strongly dissolved in the latest stages of the mineralization process.
One exceptional pseudomorph cabinet size specimen of standing mineral formations of quartz developed on anhydrite, lately dissolved and followed by sphalerite – marmatite, pyrite, and chalcopyrite.
One extremely rare specimen showing both varieties of sphalerite – cellophane (cleiophane) and marmatite. The large green transparent to translucent sphalerite – cleophane isometric crystal, was developed on quartz and galena and lately was overgrowth by small black opaque tetrahedral crystals of marmatite, which shows the evolution in feeding hydrothermal solutions.
A very aesthetic cabinet size specimen of transparent well-formed quartz crystals, overgrowth by black and very lustrous sphalerite-marmatite crystals overgrowth by very well terminated lustrous pyrite crystals
An excellent specimen of Sphalerite overgrowth by chalcopyrite– Size: 52 x 38 x35 mm Weight: 59 grams – A specimen that you receive may look slightly different in color from the one on the photographs. Because of the lights used to make the photos. – Thank you for visiting our shop! If you didn’t find what you’re looking for or you have any questions. Please don’t hesitate to contact me.

One amazing specimen of a very well terminated cluster of black and very lustrous sphalerite-marmatite crystals, overgrowth by galena crystals, lately strongly dissolved to nearly amorphous shape.
