Perfect, sharp and well-formed classic habit for a Serifos Quartz. The two side crystals are also sharp, slender and perfect. This locality has been famed for many years and still occasionally produces fine Quartz, but such clean tips have always been rare.
Colorful and classic Tsumeb specimen with flower-like sprays of light yellow Mimetite on a field of green Malachite balls. The specimen is quite richly covered and the Mimetite is well-distributed. One of the many reasons that Tsumeb is such a revered locality is the amazing diverse combinations of mineral species, elements, alterations and forms that are sometimes very esthetic. This is a choice example of these lead and copper species together. In very good condition as seen. The surface has hundreds of Malachite balls which with close exam are seen to be in the shape of Cuprite crystals (dodecahedral form) covered and altered to Malachite with a botryoidal surface. This alteration is very much like the classic Chessy, France pseudomorphs but with a different texture. An excellent display quality specimen with lots to see on it.
Very fine Rhodochrosite on Quartz from the famed Wallace Gould Levison (NYC, USA) collection obtained by trade in 1894 from a Mr. Gruzig. The large matrix holds an open cavity with Rhodochrosite balls and sparkling small crystals mixed with Quartz. The original locality listed in Levisons collection ledger calls the locality Sieben Geberge in Hungary. He later amended his label to Felsobanyo, Hungary. This is now Baia Spirie, Romania. This period was a dynamic epoch in the Austrio-Hungarian Empire, so localities were often renamed as borders, languages and nationalities changed. No matter the locality changes, this is a very well-formed specimen in excellent condition. The original Levison handwritten label is attached to the piece, and we also include a photocopy of this page from his collection notes/ ledger. Levison was an important American mineral collector and inventor (first patented movie camera etc). This piece is his number 1407 from a collection that eventually reached over 5,500. In addition to being an attractive specimen this has well-documented provenance and a good historic pedigree. Better and a little more vivid in person.
Scheelite on Muscovite
stock #AX-5-066
Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan Province,
China
7.6 x 5.8 x 3.9 CM (cabinet)
price: $1450
Fall 22
Fine deep orange-red Scheelite crystal on Muscovite matrix. This is an early specimen, ex Shields Flynn collection, that is the most rare and desirable color for Chinese Scheelite. The crystal is 3.2 CM across and lustrous, translucent to transparent. One lower corner has contacts where Muscovite blades grew into the Scheelite, the rest is in excellent condition, sharp and undamaged. As far as I know all Scheelites worldwide are fluorescent, usually a whitish blue. This one is more a yellow to orange color and is quite unusual. Overall a bright and attractive specimen with exceptional color.
Cyanotrichite

United States
8.8 x 7.3 x 3.9 CM (cabinet)
price: $150

A large matrix hosts several vugs and seams of rich blue Cyanotrichite crystals. The Cyanos are mixed with sparkling Quartz crystals, so the specimen has a bright luster as well. Best appreciated with magnification, the specimen is a nice example of the specie.
Fluorite
stock #AX-10-584
Monarch Mine, Black Rock District, Yavapai County
Arizona,
United States
5.9 x 4.1 x 3.9 CM (cabinet)
price: $150

Fluorite octahedrons in a cluster from a seldom seen Arizona locality. The largest crystal is 2.4 CM diagonal and all the crystals show a whitish frosting on mint-green faces. There is at least one old repair on the specimen which keeps the cost down, but overall it still looks nice. The mine closed in 1944, and this is an unusually large and sharp example for the locality from what I have seen. The frosted crystals still show good green color, many examples from this mine were fully overgrown with white Quartz and few had much color. The Fluorite is long wave fluorescent.
Galena with Calcite, Quartz etc.

Dalnegorsk, Kavalerovo Mining District
Primorsky Kray,
Russia
8.1 x 4.6 x 3.1 CM (cabinet)

Fall 22
Esthetic Galena crystal that is well-exposed, sits at the top of mixed specie matrix. The main Galena is complete, sharp with some face etching, and is a modified cubo-octahedral form. From the famed mines of Dalnegorsk, which has been the source of some of the world's best Galenas. Displays well from almost any angle, there is no damage seen, and the luster ranges from satin to mirror bright.

A half nodule of classic Fairfield Utah Phosphate minerals. An older specimen from the era of Over and Montgomery (1930s) at the Green Monster Mine, this is lightly polished and shows well-defined banding of species. The white core of this is likely Fluorapatite but it has not been analyzed.
