The baryte specimens of this Italian mine, which finished its work in the 80's, are considered among the best European classics for the species. This specimen presents a rich group of tabular crystals, with sharp edges and faces, excellent transparence and a superb toasted honey color. It emphasizes among them a crystal of more than 5 cm. Nowadays it is very difficult to find these samples with this quality. An European classic.

Size: 8.7 x 4.5 x 4.0 cm.
Main crystal: 5.3 x 2.7 cm.

On a matrix of stalactitic goethite, with a deep brown color, numerous prismatic crystals of pyromorphite are disposed, many of them doubly terminated, between translucent to transparent and with a delicate green color. The specimens of this Italian mine are very unusual in the market. Very interesting and aesthetic speciumen.

Size: 5.3 x 5.0 x 4.5 cm.

Excellent native copper specimen from this Italian mine. A dendritic growth of small crystals of copper, with defined edges and complex faces. The color is very intense and its luster is more than remarkable. The locality is uncommon for native copper.

Size: 6.5 x 4.5 x 5.0 cm.

A very uncommon species. It is an aluminum manganese silicate found in few localities worldwide. Specimens from Molinello mine are the best known. In this sample we observe a vein of sursassite with a coppery brown color, formed by many needle like crystals. In the quartz vug we can see perfectly formed crystals. The analysis will be sent to the buyer. A very good opportunity.

Size: 7.4 x 3.7 x 3.2 cm.

Glaucophane is an unusual species member of the amphibol group. This Italian locality is known worldwide for the good specimens of this species. It is usually covered with calcite, which once removed shows sculptural aggregates of striated tabular to prismatic translucent crystals, with an intense bluish-gray color, almost violet. In the cavities appear small orange crystals of rutile and groups of chromian muscovite (var. fuchsite). Pyrite crystals also can be found. A good sized and very aesthetic combination from this classic locality.

Size: 7 x 6.4 x 5.4 cm.
Main crystal: 18 mm.

Really fine specimen, with good size, for this rare species. The balangeroite is a magnesium, iron anfd manganese silicate, only found in a few places worldwide. The serpentine Poggio San Vittore quarry, which were the best samples has been found and it is the type locality for the species, is abandoned since 1990.
The mineral usually appears included in the serpentine matrix and only few fibers are aerial. In this specimen, fibers are totally aerial and with an unusual length. A definitive piece, from the TL for selected displays.

Very rich group of anglesite crystals, which show very good transparence, defined faces and edges, formed by first and second order prisms. They are disposed in a cavity of the galena matrix. From a classic Italian locality from where it is not easy to find anglesite specimens of this quality in the market. It comes from the former collection of L. Daunis (Barcelona) with handwriten label.

Size: 6.0 x 5.5 x 4.0 cm.
Main crystal: 15 x 4 mm.

This specimen is from a former Italian collection of early last century, G. d'Anna. It is known that a so called Giusseppe d'Anna of Telve was a military hero of World War I (see minrec). Also accompanying label store minerals Freiberg Mining Academy (more info). This fact and quality make this sample very special. The piece presents a prismatic crystal of cerussite embedded in a galena matrix. A very interesting and historic specimen.

This sulphur crystal specimen comes from one of the most worldwide famous mine for this element in the province of Agrigento. Nowadays it is difficult to find crystals of this size and less with a reasonable price. It shows very well defined faces and typically rounded edges. The yellow color is very intense, bright and with a remarkable transparence. To add value to the sample we observe various bituminous inclusions into back side. Good size and gem quality.

Size: 4.5 x 4.0 x 3.4 cm.

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.

This pyrite crystal is disposed very aerial on a brilliant hematite and pyrite matrix. It is not always usual find specimens from this Italian mining area placed on the matrix. Pyrite crystal shows pyritohedron classic forms with complex growths on faces. Its luster and gold color is good and it shows defined faces and edges. An excellent opportunity to have a sample from this classic locality.

Size: 6,0 x 5,3 x 4,8 cm.
Main crystal: 50 x 38 mm.

A very brilliant sulfur crystal disposed on a white dolomite and marble matrix. Well defined faces and edges, a little bit curved, good transparence and excellent classic yellow color. These specimens appear in vugs inside the Carrara marble quarries and it is not easy to get them without breaking them. An Italian gem.

Size: 6,6 x 4,6 x 4,2 cm.
Main crystal: 4 x4 mm.

Sulphur 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 sulphurs. 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.

A high quality and sized specimen 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. Undamaged crystals and on snowy white marble matrix, partially covered by tiny crystals of calcite. An Italian gemm...
