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.

Size: 5.7 x 4.4 x 3.4 cm.

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.

Size: 7 x 5 x 1.8 cm.
Found in 2021-22.

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.

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.

A huge size specimen formed by a large group of brilliant pentadodecahedron pyrite crystals. With an excellent luster, gold color and very well defined faces and edges. On a solid matrix of hematite crystals. A specimen for the best display.

Size: 10,5 x 10,0 x 6,5 cm.
Main crystal: 36 x 32 mm.

Sulfur crystals from the marble quarries of Carrara are appreciated worldwide for its gem quality. In this specimen, we offer a sulphur crystal perfectly disposed on the marble matrix. This crystal is very rich in complex well-defined rhombic faces. It is uncommon because they appears usually rounded. The brilliance and transparence are incredible. The color is intensely yellow, very characteristic of these Carrara sulfur specimens. An exceptional and definitive displaying sample, very rare on market, considering that in last years it has been found only few specimens of this size and quality. A great opportunity.
