Late Summer 2018
Dozens of lustrous wet-look Wulfenites are clustered in recesses on a complex matrix. Several of the Wulfenites are transparent on close exam, and they contrast well with the Calcite, Dolomite and a few colorless Quartz crystals. Most of the specimen is in fine condition but close (10x magnification) finds some small areas of chipping. By eye a strong display piece with good contrast and color. Ex Immer Cook collection, this was obtained from Schortmanns Minerals more than 40 years ago.
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.
Barite with Calcite and Chalcopyrite
stock #18.1-324
Niobec Mine, St Honore
Québec,
Canada
5.1 x 3.5 x 1.7 CM (small cabinet/large miniature)
price: $160
Late Summer 2018
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.

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.
Shattuckite
stock #AX-14-244
Kaokoveld Plateau
Kunene Region,
Namibia
6.8 x 5.1 x 3 CM (cabinet)
price: $350
Late Summer 2018
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.
Kammererite- Brilliant red-purple crystals
stock #AX-30-033
Kop Krom Mine, Kop Daglari
Erzurum Province,
Turkey
7.8 x 3.8 x 2.4 CM (cabinet)
price: $1100
Late Summer 2018
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.
Cerussite covered by Pyromorphite
stock #0097-JM-3854
Schapbach, Black Forest, (Wolftal)
Baden-Wurttemberg,
Germany
7.2 x 5.9 x 3.2 CM (cabinet)
price: $390
Late Summer 2018
Exceptional quality for this less well known locality. The matrix is almost all Cerussite in many crystal forms, with a small area of Galena nearly all covered with tiny Pyromorphite crystals. The matrix also has a dusting of very tiny clear Quartz in doubly terminated crystals that add a lot of sparkle. There are other Phosphate minerals on the specimen that are not identified. The Pyromorphite ranges from pale yellow to green hues and the whole is very colorful. The shapes of some Cerussite twins are well defined but brightly colored by the coating of pyromorphite. This all makes a very fine look under magnification. Ex John Marshall, Heinz Stempel
Chrysoberyl -classic, co-type locale
stock #18.1-407
Chrysoberyl Locality, Middlesex Turnpike, Haddam
Connecticut,
United States
2 x 1.7 x 1.5 (thumbnail)
price: $450
Late Summer 2018
A small but significant Chrysoberyl from the Haddam Connecticut locality that was the first place the mineral was found in situ in 1810. Mindat offers a detailed report on this long closed locality that makes great reading.
https://www.mindat.org/loc-213971.html
The main Chrysoberyl on this matrix is .8 CM and is sharp, translucent and a good yellow-green. Ex Larry White collection, these old Chrysoberyls are not often available. The collecting was most active in the early to mid 19th century and it seems by 1901 the original spot was no longer accessible. A choice classic thumbnail for this important locality.
