Covellite with Pyrite Quartz
stock #18-AX-30-047
Leonard Mine, Butte, Silver Bow County
Montana, United States
4.8 x 4.3 x 3 CM (miniature)
price: $850


While Covellite is a fairly common Copper mineral, crystals are very rare and good crystals are really only known from two locales (Italy and Butte) both locales are gone forever, these are true classics. A nice old Leonard mine Covellite with several free standing crystals and choice patina. This has a vintage label (1940 era?) from Continental minerals. The Covellites on this piece are of the thin blade type, very delicate and are well intergrown. The iridescence is a purple to blue with some reddish hints, this displays especially well under strong lighting as the metallic patina is very bright. Much better in person.
Pyrrhotite rosette on Arsenopyrite
stock #6.2-885
Yaogangxian Mine, Yizhang County
Hunan Province, China
4.2 x 3.6 x 3.2 CM (miniature)
price: $750


A flower form composed of thin blades of Pyrrhotite crystals esthetically perched on sharp crystals of Arsenopyrite. A rare specie from the famed Yaoganxian mine these were found almost 2 decades ago, we have not seen any since. The main flower is 3 CM across with a dark metallic patina. The Arsenopyrite crystals are highly lustrous and sharp. Overall in fine condition, one edge of the main flower has what seems to be a small old rehealed break or edge contact, not at all distracting, otherwise the display side is perfect. A very choice Sulfide from anyplace and a superb piece for the legandary Yaoganxian or for that matter all of China.
Fluorite -deep purple -fluorescent red
stock #19.1-758
Mina Ojuela, Mapimi
Durango, Mexico
4.7 x 3.6 x 3.1 CM (miniature)
price: $330


Rich "royal purple" cubes on a contrasting gossan matrix from the prolific Mina Ojuela. Excellent transparenc with lightly etched faces this has the best color that can be found at this locality and has the rare brilliant red fluorescence that makes this Fluorite unique. In great condition as seen, the display side is undamaged there are some contacts on the backside only and not seen. Choice and eyecatching, the red UV response is especially strong on this specimen.
Adamite
stock #17.1-616
Mina Ojuela, Mapimi
Durango, Mexico
4.3 x 3.2 x 1.5 CM (miniature)
price: $130


Bright lemon-green color Adamite crystals with grading to colorless near their base. These are sharp and lustrous with very good relief from the matrix. Ojuela has produced vast numbers of Adamites in many hues and habits, these are modern classiocs and quite affordable compared to the mineral from anyplace else. A sparkling miniature of well developed crystals and choice, less common color.
Smithsonite -Purple
stock #17.1-598
Choix, Municipio de Choix
Sinaloa, Mexico
4.3 x 3.4 x 1.4 CM (miniature)
price: $260


A purple Smithsonite with distinct botryoidal structure and an elegant sculptural form. Purple is perhaps the rarest Smithsonite color and not known from many other localities. From the early finds by Benny Fenn this is a nice miniature that looks fine from either side. Sadly this locality is no longer working as it is quite dangerous at this time. In excellent condition as seen, a nice addition to any suite of Smithsonite or of Mexican minerals.
Adamite (Cuprian)
stock #19.1-877
Mina Ojuela, Mapimi
Durango, Mexico
4.5 x 3.4 x 2.6 CM (miniature)
price: $260


Rich color and bright luster, a fine druse of sharp Adamite crystals on a Gossan Matrix. A few small Calcites and some areas of Conichalcite are also present. The Cuprian Adamite from here are now considered the worlds best by far and can be very esthetic. For years Cuprian Adamite was also known from Tsumeb and was also very attractive but recent studies have shown those should in fact are Zinco-Olivenite. This miniature has two well-crystallized areas that are on opposite sides of the matrix. This specimen is in excellent condition the blue green color is especially bright and this has a good display impact despite the small size.
Legrandite with Smithsonite etc.
stock #18.AX-10-952
Mina Ojuela, Mapimi
Durango, Mexico
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.
Fluornatromicrolite with Topaz on cleavlandite
stock #18.1-771
Urandu Mine, Shigar Valley, Skardu District
Gilgit-Baltistan, Pakistan
4.7 x 3.4 x 3.3 CM (miniature)
price: $1950


A superb gemmy Microlite crystal with very lustrous faces and good color. These were tested to be Fluornatromicrolite but they are also often labeled as "Microlite group" which is a bit less exact. No matter the name, the quality and large size is exceptional and the addition of glassy clear Topaz on the specimen adds some interest too. It is rare to see a crystal so perfect and at 1.5 CM it ranks as a giant for this usually non esthetic specie. From the Urandu mine finds of 2017, this is as fine as has ever been found in Pakistan and for that matter worldwide.
