thin needle quartz with pyrite, galena and sphalerite

A beautiful and very aesthetic specimen in cabinet size presenting almost full paragenesis set of Madan. Specimen is build in sphalerite, galena and pyrite overgrought by very thin, long axes quartz needles forming space developed net with quartz stars. In the late stage of crystallization were formed small pyrite crystals, used as a seed for developing of transparent quartz crystals,after deposit on galena, pyrite and sphalerite crystals continue their development forming an excellent space net.

Quartz „flower“

An well terminated quartz crystals, developed from one center and cluster look like a flower. Cluster is well space developed, and form circle structures.

Quartz pseudomorph after calcite

An excellent miniature specimen showing a „cast“ of quartz, covering steep scalenohedron crystals, secondary completely dissolved.

„Quartz flower“

A very aesthetic quartz – rock crystal developed on the top of rhodochrosite spherulite aggregates

Quartz – japanese law twin with celestine

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
