Fluorite on Stibnite
Banpo Mine, Dushan Co., Qiannan Pref.
6.7 x 6.7 x 3.5 (cabinet)
Purple to blue "melted" or tiny rounded crystals of Fluorite are covering a radiating mass of metallic Stibnite crystals from a find at Dushan almost 20 years ago. Similar to the Fluorite on Stibnite from Thailand that was found nearly 50 years ago, these are the only discoveries ever made of this sort. and both were small. Fluorite on Stibnite like this are only rarely found in the mineral market today. This is a choice small cabinet with most Stibnite having sharp terminations seen where they extend from the enclosing Fluorite. The backside of this piece has some minor bruises but that side is less attractive regardless, the front is showy and displays perfectly.
Adularia with Chlorite
St Gotthard, Central St. Gotthard Massif, Leventina
8.7 x 6.4 x 3 CM (cabinet)
Fine Swiss Adularia crystals up to 2.4 CM with green zoned inclusions of Chlorite are well presented on the matrix. From the type locality (St Gotthard) Most of these crystals have a slight dusting of Chlorite on the outside as well but the majority of the faces are glassy and transparent. Very pleasing esthtetics from almost any angle this is a choice and showy specimen of a usually unimpressive specie. No damage which is incredible for a piece with this complexity. Excellent Alpine classic that shows the textbook monoclinc form perfectly.
A super impressive and very unusual radiating fan or "wheatsheaf" clustering of chisel terminated Barite. Frizington Barite (or Barytes) is one of the great classics on the mineral world. One of the special features of good Barite from Frizington is their Bicolor nature. On this piece zoned inclusions of Hematite give a red color to edges of the prisms while the core and some terminations are a bright blue. Only some very minor edge wear can be seen and is not evident on display, overall in excellent condition which is impressive for an old classic.
Amazing form and structure on this remarkable specimen. The core of this is a doubly terminated Quartz that has a narrow waist forming the scepter and also has the "jacare" steps and faces along some faces, and some smoother "bending" on others. The addition of the stacked flat Calcites gives contrast and adds a nice pink color. The Quartz are clear to milky but have many inclusions that add a bit of color and interest. The overall form and presentation is unusual even for Huanggang which has produced some wonderful and unusual Quartz over the past few years. Choice.
Amethyst- conjoined scepters
Orange River, Namakwa
2.1 x 1.4 x 1 CM (thumbnail)
A sweet thumbnail of sharp transparent Amethyst scepters that share a single stem. Both crystals show a double termination and grade to colorless lower down. From a find a few years ago at Orange River (Namibia), there were not many of these. In fine condition as seen, and a bit nicer in person too.
Gem clear Datolite crystals up to 2.3 CM are complexly mingled with doubly terminated "Cumberland habit" Quartz and clusters of very sharp twinned Sphalerites. It is possible to see greenish inclusions inside some Datolites. This is a rich, undamaged multi specie specimen from Dalnegorsk, that is especially fine in person. The more this piece is examined the more remarkable details are seen. There are many good Dalnegorsk specimens available in all price ranges, this is especially fine and well worth the cost for a superior specimen.
Silver - very pure crystalline mass
Mass Consolidated Mine, Mass City, Ontonagon County,
5.3 x 4.7 z 3.2 CM (small cabinet/ large miniature)
A complex mass of crude crystals that have very clearly formed in a conglomerate type matrix that is now gone. This is a sponge-like cluster yet very solid and intricate. The patina ranges from a dark near black on some edges grading to a more silvery metallic in the center. I have not seen many specimens from the Mass mine but all have this spongy look and this is the best example in my limited experience. According to Mindat the mine closed in 1919. A really different looking Silver that displays fine on all sides. 78 grams.
Fluorite and Quartz
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
6.3 x 5.6 x 4.3 CM (cabinet)
The main Fluorite cube is very sharp, multi colored (blue, green and with amorphous zones of a violet purple). The main cube is 4.7 CM on edge and has very sharp corners. The Fluorite is perched on a pair of Quartz crystals and is contacted / incomplete on the back side but undamaged and choice from the front and sides. A zone of golden colored suphide druse is noted on one face that adds a nice contrast. Good rich color and transparency, a nice Yaoganxian specimen from the period when the mine was still working at full capacity.
