5.0 x 3.4 x 3.1 cm. A striking, very aeshetic row of highly lustrous and striated, metallic-gray enargite crystals from the Pasto Bueno District of Peru. The sharp crystals are all fully terminated and pristine. This is an outstanding example of the species and locale, as enargite in this quality is rare from Pasto Bueno, which is much better known for its world-class hubnerite and rhodochrosite specimens. Ex. Tarnowski Collection.
7.8 x 4.5 x 2.8 cm. A very rich and fine ore specimen from the famous mines at Butte. Several clusters of moderately lustrous, grayish-brown enargite crystals are nicely scattered atop the mounds of lustrous, black sphalerite crystals. Most of the sphalerite has a light coating of iridescent blue and magenta bornite. The matrix is quartz with pyrite. Classic, old-time and very rich ore from this noted locale. Ex. Meieran, Zigras and Tarnowski Collections.
The top of this specimen is COVERED with SHARP, well-formed crystals to over a centimeter. This is an old specimen, and should be quite desirable to those who appreciate what it is. I think it is a pretty good one! 9 x 8 x 4.7 cm
5.5 x 5.5 x 2.0 cm. Although the Sweet Home mine is most famous for it's Rhodochrosite specimens, there are several good sulfide species from this prolific locality that do not get enough attention. This piece is one of the best Enargites from the Sweet Home that I have encountered. A few sharp, striated, isolated, metallic grey-black, tabular crystals measuring up to 1.5 cm sit atop a matrix of crystallized grey-white Quartz with associated bright metallic pyritohedral Pyrite crystals. The specimen is from the well known Colorado collection of Richard A. Kosnar, and is accompanied by a Colorado School of Mines label. The specimen is 40-50 years old.
9.5 x 8.1 x 3.8 cm. A large and impressive old-time classic cluster of enargite from Butte. This specimen consists of a large grouping of sharp, lustrous enargite crystals accented by tiny pyrite crystals and small spays of quartz crystals. There are some damaged crystals but the vast majority are terminated. Ex. George Elling Collection.
You couldn''t ask for a much better enargite mini than this -- with sharp, stacked terminated crystals, beautifully defined. This piece came out of the Don Belsher collection, recently dispersed. 3.9 x 3.2 x 1.9 cm
An old Butte enargite cluster with very well-defined, shiny crystals to over 2 cm! 4.8 x 3.2 x 1.8cm
An EXCELLENT, old-time Butte specimen of lustrous, mirror-finish, brass-yellow, partially iridescent pyritohedrons to 1.2 cm with lustrous, iridescent purple, enargite crystals to 0.7 cm. The snow-white cluster of selenite blades really adds character to this piece, which is glued to a cut piece of gold-painted plywood. The scattered damage to this classic Butte combination piece is certainly not detracting. Ex Richard Hauck Collection. 7.1 x 5.2 x 4.0 cm
An EXCELLENT, old-time Leonard Mine combination piece dominated by lustrous, striated enargite prisms to 1.4 cm with nicely contrasting needle quartz crystals and lustrous, brass-yellow pyritohedrons on massive pyrite matrix. The major enargite crystals are pristine and the minor periphery damage is certainly not detracting. 6.9 x 5.7 x 3.5 cm
An old classic Butte enargite with fine, sharp crystals to 2.5 cm, distinguished by bright little pyrites which decorate the sides of the enargites. A very 3-dimensional cluster that is interesting from all sides, with just a bit of matrix attached. SUPERB freestanding xls for the locale! 4.2 x 3.5 x 3 cm
An aesthetic cluster of sharp enargite crystals, of a fine gunmetal luster, with the characteristic blunt terminations. The crystals measure to about 1.3 cm. There are a few missing crystals down amongst the cluster but not enough to detract significantly. This aesthetic miniature-sized specimen came out of the Don Belsher Collection last year. 4.2 x 3 x 2.5 cm (ex. Don Belsher Collection)
A huge, rich specimen with thick crystals of enargite measuring to 2 x 2 x 1 cmm in size. This is unusually large and stout for teh species, and its a hefty, impressive specimen overall 10.6 x 8.6 x 4 cm
ex. Martin Zinn
On eof the rare copper species, luzonite is especially desirable from this now defunct quarry in Taiwan, where it has replaced enargite to make tese big, chunky crystals. This is an exceptional piece for the crystal size. Zinn value was $1250
A classic American specimen, one of just a few pieces in this collection from our hemisphere. It is actually a ncie piece, with robust, classic dark black crystals and minor pyrite in association. Although there are a few dings, on a few crystals, it is generally in good shape.
ex. Philadelphia Academy of Natural Sciences
A hefty piece of , basically, ore. It has a pocket with a few very sharp crystals of enargite of unusual form, mistaken once for luzonite.
