RM878   Native copper

Molinello mine, Ne, Genova, Liguria, Italy

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.

 

RM1024   Sursassite with quartz

Mina Molinello, Val Graveglia, Ne, Genova, LigurĂ­a, Italy

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.

Analyzed specimen with report
 

RM1202   Tinzenite with quartz

Molinello Mine, Val Graveglia, Ne, Genova, Liguria, Italy

Groups of orange rosettes of this rare species. Tinzenite is a boro/aluminosilicate of calcium and manganese from the axinite group [see here], and probably the best specimens are from this Italian mine. Also accompanied by quartz crystals.


Size: 8.3 x 7.0 x 4.8 cm.
Found in 2011.

 

RM1239   Tinzenite with quartz and kutnohorite

Molinello Mine, Val Graveglia, Ne, Genova, Liguria, Italy

Groups of orange rosettes of this rare species. Tinzenite is a boro/aluminosilicate of calcium and manganese from the axinite group [see here], and probably the best specimens are from this Italian mine. Also accompanied by quartz crystals and white to pink kutnohorite aggregates.
