Quartz included by Hollandite stars
Ambatofinandrahana Department, Amoroni Mania Region
10 x 5.6 x 2.8 CM (cabinet)
A pair of closely joined Quartz prisms showing star inclusions of Hollandite. The main crystals growing from a cluster of smaller Quartz and are clear enough to clearly see the radiating bursts of dark Hollandite crystals. From finds over 15 years ago, these are not being found anymore as far as we know. The Quartz is also in very good condition, most of the other specimens in the find had significant chipping. A nice addition to a Quartz suite or any collection of inclusions.
2.7 x 1.5 x .5 CM (thumbnail)
A crystalized thumbnail of Cornish Torbernite with a bright apple-green color. Ex Dr T.B. Wilson collection, we do not have a mine attribution for this piece although it looks like a great match to Old Gunnislake Mine, but that is not documented. There are many Torbernite locales listed in Cornwall, most have crude plates or scattered crystals, relatively few have rosettes and dense clusters. A colorful English piece that is reasonable in cost yet choice.
A really fine, large, heavy and rich Ruby Silver from the classic locality of Freiberg. Two large faces are densely encrusted with many dark to bright red crystals in several habits, and whole dosplays well from several angles. A few crystals have typical bruises the vast majority are perfect and the condition is far better than most of these old and delicate pieces. Some dark native Silver is also noted on the matrix. Displays well from several angles, the old label which had been affixed to the piece is damaged and incomplete but the word Frieberg is clear. We are informed that this matrix, habit and style is a perfect match for the Himmelsfurst mine and is clearly a very old piece. The Pyrargyrite is still a good red color despite the age and some darkening, much better than usually seen on these. The Pyrargyite is also set off by some associated milky Quartz and Calcite so it really stands out on display,. The crystals and rounded masses also are protruding well from the matrix which adds a good texture. A very choice, large classic European Ruby Silver that is especially fine in person.

Serifos Island, Cyclade Islands
5.5 x 3.1 x 1.7 (small cabinet/large miniature)
A cute classic Greek "Prase" or "Prasm" Quartz with good green color, translucence and sharp tapering crystals. Serifos Quartz has been a long known and collectable variety, it has a very distinctive habit that is only known from a few other skarn deposits worldwide. These have become quite pricy on the market, this one is in good shape, has only very tiny chips that are hard to see by naked eye, and is very reasonably priced for one of these.
A juxtaposed pair of "butterfly" twin Calcites with bright faces, fine clarity and red Hematite phantoms. From the last mining at Leiping, these are excellent examples from this locality. These twins made big news in the mineral world when found in 2002, partly because they looked so much like the classic British twins from over a century ago. Sharp. clean and elegant these are modern classics that look like the vintage old world classics.
A rare, choice gem clear thumbnail of lilac color Hexagonite (var of Tremolite). The termination on this is complex being made of many tiny points in a tapering structure. Transparent with some color zoning seen when backlit. I believe that St. Lawrence County is the only place where this mineral occurs being found at just 4 locations. However only the Gouverneur Mine ever produced any of this sort of clear terminated crystal and not many of them. This was named when it was thought the crystal form was Hexagonal, however it was later determined to be Monoclinic. The crystal here is in fine condition, has clear striations along the prism faces and a very rich color.
From the "golden age" of mineral finds at Yaogangxian, this is a super choice Stannite. Ex Shields Flynn collection, the Stannites are bright brassy, well formed, undamaged and very rich. This specimen was exhibited at Tucson in the TGMS displays in 2005 celebrating the minerals of China. Most pieces from this find had much more Arsenopyrite and or Sphalerite than Stannite, this is almost all Stannite with clear Quartz crystals adding a nice accent. Most will agree that the old Yaogangxian finds were the best ever found. This specimen is well better than typical and now Chinese Stannite is rarely available in such size and attractive quality.
Elbaite -Rubellite gem crystal
Cruzeiro Mine, Sao Jose de Safira
3.5 x 1 x .7 CM (small miniature/ large thumbnail (toenail))
100 percent gem grade Rubellite, mostly a fine cranberry red color with a lightly yellow zoning at the termination. An older Cruzeiro (Brazil) crystal the color is unusually intense for this locality, this looks similar to some Santa Rosa and Jonas mine crystals yet has a sightly different hue. In excellent condition as seen, with even a little backlighting this glows like red glass. The inside is very clean, this is all facet grade that has avoided the cutting wheel. Choice and better in person. Ex John Buckley collection we think this is a 1970 era piece.
