An excellent miniature specimen showing a „cast“ of quartz, covering steep scalenohedron crystals, secondary completely dissolved.
A very aesthetic quartz – rock crystal developed on the top of rhodochrosite spherulite aggregates
An extraordinary specimen of clear- rock crystal quartz, with several well-presented Japanese law twins. In the late stages of the crystallization process, were developed several groups of gold color groups of needle celestine crystals
An attractive specimen of well-terminated pyrite with very lustrous crystal faces, singenetically developed with transparent quartz – rock crystal and followed by sphalerite and galena.
A specimen of shiny small galena and sphalerite crystals, followed by bigger pyrite crystals, particularly oxidated and coated by bornite. All these minerals are covered by extremely shiny, long-axes, needle quartz crystals, very well space developed and forming a set of crystals
An excellent double-terminated scalenohedron calcite crystal build by the alternation of calcite and calcite aggregates.
A very attractive specimen, presenting very well space developed long-axes transparent needle quartz, covering sphalerite, galena, and pyrite crystals
A unique for Bulgaria specimen presenting space developed transparent quartz – rock crystal with very well terminated shiny pyrite crystals coated by iridiscenting bornite and covellite as result of oxidation of , most likely coating of chalcopyrite
The most attractive, cabinet size specimen of emerald color sphalerite -cleophane from Androvo mine. The strong colored transparent crystals are developed on the top and between long-axes quartz crystals.
A beautiful specimen presenting well-terminated galena cubic crystals, covered by chalcopyrite and sphalerite-marmatite with green quartz on the top.
