MD-169966 - Ullmannite - - Archived Masaloni Mine, San Vito, Cagliari Province, Sardinia, Italy small cabinet, 5.4 x 3.3 x 2.1 cm.
5.4 x 3.3 x 2.1 cm. This superb rarity features SHARP and LUSTROUS crystals to a full centimeter, perched up in a mound to make for a very attractive specimen of this usually not very attractive species. Sarrabus is a very important, ancient silver district. Ullmannites are one of those rare bystanders that so sadly, few were saved of. What is amazing about this specimen is that the piece actually has some display aesthetics whereas most are embedded in massive, ugly ore. From the collection of Gianguido Giannobi.
MD-239917 - Ullmannite - - Archived Storch und Schöneberg Mine, Gosenbach, Siegerland, North Rhine-Westphalia, Germany miniature, 4.8 x 3.1 x 2.5 cm.
4.8 x 3.1 x 2.5 cm. Ullmanite is a rare nickel, antimony sulfide that forms in the isometric system. This specimen of solid ullmannite is from the Type Locality in Germany and is embedded with highly lustrous, metallic-gray, platy crystals that reach .6 cm across. This is rich and incredibly important example from this classic locality. Ullmanite, in good crystals, occurs very rarely. This old-time specimen is accompanied by three labels. Julius Bohm, one of the most important of the early Viennese mineral dealers, opened for business in 1884. His label with the piece dates from 1925-38.
MD-54377 - Ullmannite - - Archived Masaloni Mine, San Vito, Cagliari Province, Sardinia, Italy thumbnail, .6 cm
Ullmanite is a rare nickel, antimony, sulfosalt, that forms in the isometric system. This matrix piece is studded with DOZENS of highly lustrous, metallic gray cubes that reach .6 cm across. In fact, an in-depth look at these crystals will reveal that many of them form penetration twins, just like fluorite. This is one of the richest such specimens I have ever seen for sale or know to exist, and it is an incredibly important example from this classic locality. Ullmanite, in good crystals, occurs very rarely elsewhere and the best are known from here. This piece was one of the best found in recent re-working of old mine adits by some intrepid Italian friends. 14.5 x 7.1 x 4.8 cm
RARE08-61 - Ullmannite - $ 2500 SOLD Masaloni Mine, San Vito, Cagliari Province, Sardinia, Italy miniature, 5.4 x 3.3 x 2.1 cm
This superb rarity features SHARP and LUSTROUS crystals to a full centimeter, perched up in a mound to make for one of the more display-worthy and least ugly and massive specimens of this material I have yet seen (even in museums, all of which want one). Sarrabus is a very important, ancient silver district. Ullmannites are one of those rare bystanders that so sadly, few were saved of. What is amazing about this specimen is that the piece actually has some display aesthetics whereas most are embedded in massive, ugly ore. I have seen a number of these in museums and in dispersals of old European collections, and out of all this is not the most expensive by any means , but is one of my favorites for its overall combination of qualities. From the collection of Gianguido Giannobi. All Content and Design ©1996-2010 The ArkenstonePowered by http://mineralwebsites.comBy-species Galleries | ||||||||
