An older very fine Fluorite that is a pure mass of oriented crystals all of which are modified cubo-octahedral or dodecahedrons. In fine condition, the display sides are choice and undamaged only the backside is contacted. The larger crystals are fully transparent and have very good luster. Dispalys well from several angles, this style and habit has not been available recently except from older stock (as this is). A modern Chinese classic.
Calcite -Gem clear with phantom
Leiping Mine, Leiping, GuiyangCo., Chenzhou Prefecture
4.1 x 3.6 x 2.5 CM (miniature)
Bright luster, exceptional clarity and sharp form, a choice miniature from the now famous Leiping mine. In perfect, undamaged condition, this mine is famous for these superb Calcites and the bright Hematite phantoms. Very few have been available in recent years. Similar in form and habit to the classic English Calcites from the Iron fields in Egremont, these are far less expensive yet just as attractive.
Sharp, clear prismatic crystals of Valentinite scattered on and esthetic spray of Stibiconite. The Stibiconite has fully replaced the original Stibnite but the form is perfectly preserved. Despite the delicate nature of this specie, this specimen is in excellent condition, complete and undamaged. The Stibnites of Xikhuangshan are world famed, but the less well known, alteration species (like Valentinite) are also world class. This piece is ex Shields Flynn collection and looks good from every angle.
Ferberite (rosette) and Quartz etc.
Yaogangxian Mine, Yizhang County
5.5 x 4.4 x 3.9 CM (small cabinet/ large miniature)
A 360 degree specimen hosting a delicate cluster of Ferberite crystals pointing in all directions and slender Quartz prisms. Very tiny Muscovite and a few Scheelites are also on the piece as is typical from Yaogangxian where complex multi specie specimens were typical. The longest slender Quartz is 4.2 CM and doubly terminated. Some contacting that is not very noticeable, several terminations are a ragged, complex type that adds some esthetic complexity. Very displayable and a choice piece from the locale.
A perfect main Arsenopyrite crystal with textbook form well perched above the matrix of Muscovite and Quartz crystals. Brilliant metallic luster, no damage and great esthetics, a very choice miniature for the specie. The main Arsenopyrite is just over 2 CM and has a penetrating crystal (twin) that is in a X form, but is not very evident from the logical display angles. From finds almost 10 years ago at Yaoganxian. Hard to photograph the brilliant luster, this is great in person.
Fluorite -dark zoned
Yaogangxian Mine, Yizhang County
4.1 x 3.3 x 2.5 CM (miniature)
very sharp single cube perched on a shard of matrix, mostly Muscovite. The Fluorite has very deep purple zones and masses on the outer edges the center core is transparent and a light blue color. Very glassy luster as in all the better Yaoganxian Fluorites. The display side is perfect damage wise, there is contacting and cleaves on the back. Better in person, this is from mining in the 2004-5 season when a very rich area was worked. The locality no longer produces anything like this.
Stibnite and Calcite
Xikhuahshan Antimony mine
4.3 x 3.4 x 2.3 CM (miniature)
Late Summer 2018
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.
The very best Yaogangxian Cassiterite I have ever seen, with the largest crystals as well. An excellent multi-specie piece mostly composed of superb Cassiterite. This locale has produced thousands of excellent mineral specimens but Cassiterite is very rare from this famed locale. Sharp lustrous crystals to almost 3 CM are arranged in a radiating cluster on a very complex matrix. I count at least 7 mineral species on this miniature, but the Cassiterite is clearly dominant and is in fine condition as well. A superb modern classic and a very important Yaoganxian specimen.
