Fluorite on Quartz
stock #19.1-860
Riemvasmaak, Kakamas district
Northern Cape Province, South Africa
5.5 x 3.8 x 3.2 CM (cabinet)
price: $180


A milky Quartz with a subtle phantom is a the matrix for a mass of sharp zoned Fluorite crystals. These Fluorite cubes have a blue to purple edging and white to yellow cores. This locality (Riemvasmaak) has been a well known locality for fine green octahedral Fluorites but this style and habit are far more rare. Esthetic and in very good condition, the Fluorites are about 3 mm in size. An attractive and unusual specimen, the Fluorites cover three of the faces of the Quartz, the remaining 3 faces are empty.
Cubanite
stock #13.1-240
Henderson Mine, Chibougamou
Quebec, Canada
3 x 2.3 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $625


An esthetic cluster of shining Cubanite crystals all showing classic twinningset on just a sliver of matrix. The Henderson Mine at Chibougamou has been closed for many years, it was the only source of these fine, sizable Cubanite crystals. The largest crystal in this cluster is is 2 CM across, and sits well on top of the specimen. Close exam shows some minor bruising, contacts and natural cracks, so this is not for perfectionists, but as Cubanite is a very delicate mineral this is in relatively fine condition. and far better than average. Some areas that look like damage in the photos are on inspection fully intact and crystalized with a rough texture. The metallic luster is excellent and has a nice patina. These are a modern classic and somthing of a "holy grail" for most collectors, the starburst twinning habit is especially desirable. An excellent value for the quality.
Legrandite with Smithsonite etc.
stock #18.AX-10-952
Mina Ojuela, Mapimi
Durango,
4.2 x 3 x 2.7 CM (miniature)
price: $110


Small but bright, sharp and gemmy free standing crystals of bright yellow Legrandite. These crystals line a vug with a druse of smaller more pale Legrandites as a background. A small area of Smithsonite in Scalenohedral crystals is also noted on the back of the matrix. This is an older specimen from 1970 vintage finds. Magnification reveals a few broken crystals at the edge but those in the central area are complete and perfect. A very good budget specimen.
Copper
stock #1003-JM-1428
Cliff Mine, Pheonix, Keweenaw County
Michigan, United States
16.1 x 2 x .5 CM (cabinet)
price: $220


An antique native copper "finger" or "fan blade" made by skilled hand chiseling long ago. These artifacts were made by miners from the often huge masses of pure Copper encountered in the Upper Penninsula of Michigan. From the John Marshall collection, this is recorded as from the Cliff Mine, such attributions of these artifacts are quite uncommon. Aside from the very hard labor of hammering through solid copper, these fingers required a lot of skill to create such a long straight and clean blade. While not a typical mineral specimen this is a very much a classic Native Copper that has had a major trimming job!
