Coahuila, Mexico
7.3 x 6 x 3.7 CM (cabinet)

Dec 2018

Blocky habit Vesuvianite crystals that are doubly terminated are studding a contrasting Rhyolite matrix. From very old finds at the locality once called Lago de Jaco, now Sierra de la Cruz. The Vesuvianites are well exposed from the matrix and are nearly all bi color. This habit of Vesuvianite was collected before 1980, there have been no more in recent years.

Dec 2018

A choice bright metallic Acanthite showing what seem to be twinned crystals and with a bright luster. No damage, no matrix and no contacts. A fine thumbnail with the main elongated cube of 1.2 CM. A neat small Guanajuato specimen from the most legendary old deposits of the Mexican Silver belt.
Rosasite on Smithsonite with Calcite
stock #18-AX-19-146
Silver Bill Mine, Gleason, Dragoon Mts. Cochise County
Arizona, United States
4.3 x 3.8 x 2.2 CM (miniature)
price: $90
Dec 2018

Spheres of blue Rosasite scattered on Smithsonite and some Calcite. A good locality piece that is especially fine under magnification. The Silver Bill mine has a long history but is not very well known outside of Arizona. It has been a source of Wulfenite and other species as well as Rosasite.
Brookite on Quartz
stock #18.1-454
Moses Hill, Magnet Cove, Hot Spring Co.
Arkansas, United States
3.1 x 1.6 x 1.2 CM (thumbnail)
price: $75
Late Summer 2018

Sizable Brookites scattered on a Quartz crystal from the classic locality of Magnet Cove. Choice older piece with several habits of Brookite some of which are very lustrous in person. The Quartz is doubly terminated and is the usual milky to smoky type with some signs of corrosion that is distinctive to this locale. In excellent undamaged condition.
Albite with Fluorapatite
stock #18.1-447
La Marina Mine, Pauna
Boyaca, Colombia
7.2 x 4.8 x 3.3 CM (cabinet)
price: $80
Late Summer 2018

Albite in sharp, glassy, lustrous and mostly transparent are the majority of the specimen. There are a few scattered pink Apatites, the largest about 1 CM, which are also glassy, transparent and in fine condition. From the great find at La Marina Mine, that became famed for the pink Apatites and later for some of the worlds best Euclase. The Albites were sometimes matrix for both of these species and I think under appreciated on their own, they are superb and showy Feldspars. A choice specimen that is well crystalized on both sides and shows off the Albite more than the Apatite.

Xikhuahshan Antimony mine
Hunan Province, China
4.3 x 3.4 x 2.3 CM (miniature)

A delicate and complex miniature specimen of transparent, zoned Calcite scalenohedra mixed with metallic Stibnites. In fine condition this is a very three dimensional piece. From the prolific finds of 2008-9, an affordable Calcite/Stibnite combo that is complex and very detailed.

A nice spray of flat Celestite blades hosting light yellow Calcites. The Calcite are doubly terminated and scalenohedral. The Clay Center area has been a prolific mineral locale for decades best known for Fluorite but also a source of nice Celestite. In fine condition and displays well.

The form of these Hematite pseudos is simply incredible. This is a complete floater, no damage or contacts, sharp, metallic luster and very well detailed. One of the best mineral finds of the past several years the Payun Volcano mineralogy is fascinating and the morphology of the better crystals like this is exceptional.
