Super clear, a transparent purple cube with flat proportions and edge bevels. Very attractive and lustrous, the condition is very fine, there are old contacts on some edges and faces as seen that have fully recrystallized and show fine stepped etching, there is no chipping or normal damage. A choice and richly colored single crystal fro the Llamas Quarry, this is an excellent very gemmy example.

3.2 x 2.2 x 1.5 CM (small miniature/ large thumbnail (toenail))

Spring 2019

A royal blue Halite cube is nicely perched on contrasting matrix. In undamaged condition this is a very attractive large thumbnail (toenail) from the now famous finds near Carlsbad New Mexico. The cube is transparent and has some distinct color zoning in person. The cube shows very well the "melted" surface texture.
Cassiterite, Aquamarine and Muscovite

Mt. Xuebaoding, Pingwu Co., Mianyang Pref.
Sichuan, China
8.8 x 4.3 x 3.1 CM (cabinet)
price: $1100


Exceptionally lustrous and choice specimen of Cassiterite crystals clustered with light blue Beryl (Aquamarine) and set off by well crystalized Muscovite. Ex Shields Flynn collection, this is an older Mt. Xuebaoding specimen that is unlike any of the later finds and is especially esthetic in person. In excellent condition as seen, the display face is in perfect condition the only damage is on the outside edges where this was removed. The bright glassy luster of the Cassiterites is hard to capture in photos it is really brilliant in person.

A perfect complete octahedron of the classic Chessy, French Cuprite form pseudomorphed into Malachite. This is the most iconic habit of this famed locale, and this specimen has the very distinctive hoppered faces that are so unique on these old specimens. No damage and all sides display well, this is a 360 degree piece. An excellent thumbnail with wonderful form.

Oberdorf an der Laming, Laming valley, Bruck an der Mur
Styria, Austria
7.4 x 6.7 x 4.5 CM (cabinet)

Spring 2019

An elegant, very well crystallized Strontianite from the classic locale of Oberdorf. This cluster is a floater- it is crystallized on all sides and shows two differnt habits probably formed in two generations. The individual crystals reach almost 3 CM and the condition is impeccable, with no damage to be seen. Displays very well from almost any angle, each side is very presentable. The recent detailed Mineralogical record article gives an excellent view of this remarkable deposit and the great Strontianites there. Excellent value for a choice display quality classic specimen.
Smithsonite with Aurichalcite, Calcite

79 Mine, Hayden, Banner District, Gila County
Arizona, United States

price: $330
Spring 2019

Bright green rounded crystals of Smithsonite are clustered on botryoidal mounds over the face of this matrix. Wet luster and fine form with a distinctive hue, a choice older 79 Mine Specimen. This has zones of accicular Aurichalcite crystals and Calcite that add contrast and interest. In excellent condition and a very colorful Arizona Smithsonite. Even better in person.
Selenite (very clear gypsum crystal)
stock #19.1-238
Naica Mine. Naica, Municipio de Saucillo
Chihuahua, Mexico
5.7 x 3.1 x 1.1 CM (cabinet)
price: $240
Spring 2019

Textbook perfect, sharp and transparent, a single doubly terminated Selenite from the famed Naica Mine. This is a 1970s vintage specimen in fine condition as seen. There are a few wispy inclusions that are not visible on some display angles, the exterior luster is very glassy with a few areas with very minor frosting. Overall this is a choice example. The Naica mine produced a lot of Selenite in its day. Not much that came out was this fine, most had some damage or edge issues. Now that the mine is closed these better specimens are becoming treasures.
Chalcopyrite with Quartz
stock #6.2-843
Yaogangxian Mine, Yizhang County
Hunan Province, China
4.3 x 3.8 x 3.1 CM (miniature)
price: $290
Spring 2019

We do not see many good Chalcopyrites from Yaogangxian, although it was a common mineral there. This is an excellent, complete cluster of fine sharp crystals in outstanding condition. Very well defined striations, good patina and esthetic composition, this is all in all a choice piece. For a quite common mineral good Chalcopyrites crystals of this size are rare.
