Although it is not an aesthetic specimen in the conventional sense, this metacinnabar is a very interesting for the locality and unusual piece for sale. It comes from the Pietrineri mine, a mercury mine included in the famous mercury mineral complex of Monte Amiata, currently completely abandoned. Mining operations at Pietrineri began in 1902 and ceased in 1979. In the specimen we can see the vermilion of cinnabar along with black aggregates of metacinnabar.

Specimen of hydromagnesite formed by various globular aggregates of lanceolated and transparent crystals of this magnesium hydroxylcarbonate. They stand out for their contrast with the ophiolitic rocky matrix. It is not very common to find specimens from this Italian locality.

Radiated spray aggregates of fine dawsonite crystals, a rare aluminum sodium hydroxylcarbonate. They aredisposed on a marl matrix. They come from a known area for the species but from a new find.

Specimen of anhydrite formed by numerous prismatic to tabular crystals, well defined and interpenetrated. On the back we can see the matrix formed by dolomite and brilliant pyrite crystals. Specimens from this Italian mine, located north of Boccheggiano, were collected at the end of the 20th century. The mine worked from the early 1980s, currently the mine is closed.

Very bright specimen formed by numerous hexagonal shape pyrrhotite crystals, accompanied by pyrite. A pyrite mine owned by Solmine. Closed before 1984. An old specimen from an Italian locality from where it is very difficult find specimens.

A rich cluster of hyaline quartz crytals from the famous Carrara Marble quarries of Italy. The ancients believed that water solidified in the form of hyaline quartz crystals... Viewing this specimen, its purity, transparence, brilliance and perfection, perhaps we can understand their interpretation. Snowy white marble matrix with dolomite crystals. An Italian gemm.
