One excellent thumbnail of slightly dissolved galena crystals, with isometric well developed green translucent to transparent sphalerite – cleophane crystals.
An excellent cabinet size specimen of quartz and galena, covered by very well developed tetrahedrical crystals of green sphalerite – cleophane with rarely high transparency.
One very aesthetic cabinet size specimen, presenting small crystals of quartz, galena and completely transparent crystals of light- green isometric crystals.
One amazing cluster of „barrel“ shape amethyst crystals with small sphalerite-marmatite crystals and pyrite.
One beautiful, cabinet size specimen, presenting twined isolated galena crystals, aesthetically standing on mother rock with small sphalerite-marmatite.
The small beauty. One very aesthetic thumbnail specimen of flat calcite „paper spat“ crystals developed on the top of galena , sphalerite and quartz. In the end very nice ball like, rounded with pale pink color rhodochrosite crystals were developed.
One exceptional and very rare cabinet size specimen, of sphalerite and quartz with isolated large curved rhodochrosite crystals with pale color.

One of the last pieces of Bulgarian famous cavity of transparent sphalerite – cleophane with intensive green-emerald color. The piece is completely transparent, but in its down part, there is a shadow, following the zoning of crystal development of around 10 % of the volume. The picture is taken in transmitted (back) led light.
