Kammererite- Brilliant red-purple crystals
stock #18-AX-30-033
Kop Krom Mine, Kop Daglari
Erzurum Province, Turkey
7.8 x 3.8 x 2.4 CM (cabinet)
price: $1100


A killer in person, top quality chromian Clinoclore (Kammererite) in a quality that is simply not available anymore. Outstanding, unusually brilliant, rich deep purple Kammererite in large well formed crystals. These are transparent gem grade, sharp and in perfect condition. It seems there will not be anymore Kammererite from Turkey, even average pieces are now hard to get classics. Widely regarded as the very best ever found, the Kammererites of Kop Krom stand out worldwide. Most specimens were druses of very small crystals, pretty but not exceptional. However, this specimen has many big 7-8 mm plus sized prisms on a bright druse. Eyecatching display piece that is one of the best in this size.
Proustite-classic ruby Silver
stock #18.1-322
Shaft 207, Niederschelm, Schelma, Schlema-Hartenstein District, Erzgebir
Saxony, Germany
1.6 x .7 x .6 CM (thumbnail)
price: $300


A complex single crystal of bright red Proustite and just a tiny speck of adhering matrix. Classic Ruby-Silver, from the German Erzgebirge, this has very good luster and the red color shows no sign of fading. Close exam with magnification finds some chipping but most of the crystal faces show good form with glassy striations. Much better in person, this is a choice thumbnail at a very reasonable cost for this highly desired Silver mineral.
Scapolite
stock #18.1-323
Pierrpont, St. Lawrence County
New York, United States
4.3 x 2.3 x 2.2 CM (miniature)
price: $170


A choice, sharp milky-white Scapolite from this classic NY area. Many of these have been tested as Meionite which is the more Calcium rich variety, but this has not been analyzed This was collected more than 30 years ago and is in fine condition all around, with complete termination and fluorescencent as well. This is the most sharply formed St Lawrence County Scapolite I have seen.
Shattuckite
stock #18-AX-14-244
Kaokoveld Plateau
Kunene Region, Namibia
6.8 x 5.1 x 3 CM (cabinet)
price: $350


An esthetic and pure mass of the Copper Silicate Hydroxide - Shattuckite. Very good color in a three dimensional specimen. This has a sculptural form holding an open vug much like a vase. The inner surfaces are all a delicate botryoidal blue velvet and the edges show the fibrous structure as well. From the limited finds made in 2013-5 in the Kaokoveld, These were a significant discovery at that time, and remain as some of the best specimens ever for the specie.
Calcite -light violet
stock #18.1-411
Hyatt Mine, Talcville, St. Lawrence County
New York, United States
3.4 x 2.1 x 1.7 CM (small miniature/ large thumbnail (toenail))
price: $60


A single scalenohedral Calcite crystal with a light Violet hue. Sharp with a slight milky zoning, this is in good condition as well. Calcites from this locale are not often available.
Barite with Calcite and Chalcopyrite
stock #18.1-324
Niobec Mine, St Honore
Quebec, Canada
5.1 x 3.5 x 1.7 CM (small cabinet/large miniature)
price: $160


A choice, sharp, partly transparent Barite without damage from the great pocket finds at Niobec. Nearly all of the Barites we see from this zone have at least some chipping, I am told they formed on the pocket roof and were mostly all dislodged, being damaged in the process. This small specimen has a perfect, sharp and complete termination, is dusted with tiny Chalcopyrites and has a few sharp Calcites as well. A fine example from this modern classic find.
Diamond in Conglomerate
stock #8 AE-956
Diamontina
Minas Gerais, Brazil
7.3 x 6.8 x 4.3 CM (cabinet)
price: $350


From the ancient Diamond locality of Diamantina in Brazil, a fine silvery-white Diamond crystal sits in typical Conglomerate matrix. We have heard of faked Diamond in Conglomerate so this has been tested with Acetone and other solvents, and after good exam under strong magnification this seems to be real. It matches other legitimate specimens so we cautiously have offered this. I have visited Diamantina and seen the same Conglomerate type being excavated and crushed to reveal Diamonds as has been going on for centuries. This modified octahedral Diamond is faintly fluorescent and well formed, tightly locked in a small crevice. The Diamond digging of this locality were a closely guarded operation during the years of Portuguese colonization and were a major part of the wealth of Brazil in those years. Ex A. Edwards collection.
Quartz, red doubly terminated (Eisenkiesel)
stock #18.1-412
Chella, Valencian Community
Valencia, Spain
2.3 x 1.2 x 1 CM (thumbnail)
price: $60


A choice single crystal of the blood red "Eisenkiesel" habit, complete all around. With strong bright Hematite inclusions, these Spanish Quartzes are distinctive. The local name for these is "Jacinto de Compostela" and they are unlike any other Quartz.
