SOLD Covellite with Pyrite Quartz
stock #SOLD 18-AX-30-047
Leonard Mine, Butte, Silver Bow County
4.8 x 4.3 x 3 CM (miniature)
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.
Mina Navidad, Abasolo, Rodeo
5.2 x 3.2 x 3.8 CM (small cabinet/ large miniature)
Radiating cluster of very distinct Creedite crystals that are free standing, reaching nearly 3 CM tall. Aside from the much larger than usual crystals, this has very rich color, some transparency and fine luster. Mina Navidad has been the source of nearly all good orange Creedites, a mineral usually colorless or brown (rarely purple) and usually in much smaller crystals. This is far above average miniature, excellent for the size and especially esthetic.
Rutilated Quartz and Hematite
3.8 x 2.4 x 1.8 CM (small miniature/ large thumbnail (toenail))
A cute toenail sized rutilated Quartz that sits on bladed Hematite crystals that are also Rutilated. The Rutile hairs are bright golden color and very sharp, clearly seen both inside and out of the Quartz. Rutile on Hematite and Rutile inside Quartz are both often available, but it is quite uncommon to see both together like this.
Sharp and gemmy red Rhodochrosite crystals on a contrasting matrix. The crystals are mostly formed as Scalenohedral but take a few other forms as well. Uchucchacua is one of the worlds best Rhodo localities for Scalenohedrons, but not as well known (or expensive) as South Africa. Several crystals are partly coated with a thin crust of what seems to be Calcite and makes a nice contrast.
From the type locality area for Wulfenite, this is a very choice, classic Lead secondary specimen. About a dozen distinct octahedrons of Galena are sparkling with hundreds of Cerussite crystals scattered on the faces. The spaces between the Galenas are full of orange to red Wulfenites in a blocky form. One of the great classic mineral localities, important since the early 14th century. In 1556 Agricola described the locality and methods in his famed "De re Metallica" . The mines closed for good in 1993, but left a great legacy of minerals and helped develop many methods in use today. This specimen is in remarkable condition, is far more attractive in person and a fine display quality Galena much better than most seen in collections from here.
6.2 x 4.8 x 3.6 CM (cabinet)
Sparkling pink balls of Thompsonite on a contrasting matrix- a very attractive specimen of this usually drab mineral. The outer surfaces of the balls are covered with tiny needle crystals that make the luster far more bright than most typical Thompsonite. This is from a small find about 6 years ago that was unlike any Thompsonite found before or since, and were perhaps the best specimens ever. We sold this piece some time ago it is now back and we are happy to have it. One edge of this piece has balls that show the inner structure along the side. The overall quality, color and condition is excellent and this is a super example of this more uncommon Zeolite. A colorful and attractive addition to any suite of Zeolites or Indian minerals.
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.
Killer thumbnail with intense bright color and great esthetics. A cluster of Adamite crystals showing saturated color zoning and featuring a saturated Purple sector. In perfect, undamaged condition. The back side and a few other spots have some nice small balls of Austinite as well, an unusual combination that adds a bit to the overall interest. Purple Adamite from Mina Ojuela is one of the most desired of Mexican minerals, this color and quality is found rarely and prized.
