A fine and well-developed cluster of Pyrite crystals showing deep striations and bright luster. Ex John Marshall collection, this is a vintage piece from a locality we rarely see, but which was famed for fine Pyrite crystals and some other Sulphides (Stibnite etc). In excellent condition the Pyrites are in clusters and also in well-isolated crystals. This is a solid and stable piece there is no sign of any degeneration or oxidation.

Late Summer 2021
From the famed Green Monster Mountain (Alaska) a Pyrite crystal partially pseudomorphed by Iron Oxide species. This locale is well-known for fine Epidote but the Pyrite pseudos are seldom seen. The Pyrite on this has good somewhat iridescent luster on some faces. Several faces also have some fissures and and stepped zones. The pyrite form is distinct and the specimen seems to be solid and stable.
Pyrite - elongated stalactitic ps. Marcasite

Buick Mine, Bixby, Vibernum Trend, Iron County
Missouri,
United States
7.8 x 1.3 x .8 CM (cabinet)
price: $300
Early summer 2021
A mineral oddity and a choice example of this rare form. Pyrite has formed over a former Marcasite stalactite and is an elongated, slender cube. The central canal hole is visible at the base and the whole piece is complete and terminated. Previously labeled as from Joplin, Misouri, this is quite certainly from the well-known Buick Mine in Iron County some distance away. The cross section of the piece is square and the whole thing is based on an elongated cube form. In excellent condition there is a little overgrowth of later Marcasite on the outside. The luster and color are also good, a bright metallic golden with some silvery spots.

A cluster of Pyritohedral Pyrite crystals with sharp and lustrous faces. From the famed finds on Elba Island, this is an older specimen Ex Larry White collection. The specimen was acquired from Joe Stachura in 1967. The age is important because despite more than a half century out of the ground there is no sign of tarnish, degradation or "pyrite disease" which was an issue with some from this locale. It is a brilliant golden metallic luster that is hard to appreciate on a computer screen. The crystals are clustered in an epitaxial arrangement and are in fine condition, there is just one small attachment point that sits under the specimen and it can be displayed from several different angles.

An open vug or pocket lined with Hematite blades that are the matrix for several Pyrite crystals in Pyritohedal form. Classic Elba specimen that shows well the contrast between the two species and the crystal habit that is famed from Elba. This is an older piece with the Pyrite having maintained very good luster.
Pyrite -octahedral on Quartz Classic USA
stock #18.1-506
Emma Mine, Butte, Butte District, Silver Bow County
Montana,
United States
5.4 x 4.3 x 2.7 CM (small cabinet/ large miniature)
price: $200
Octahedral Pyrite and milky Quartz in a classic combination from Butte. Additional dark sulphides are present but the main feature here is the lustrous Pyrites and elongated Quartz. In excellent condition which is rare in Butte pieces. Butte is one of the worlds greatest mining zones of the 19th and early 20th century. Good specimens are surprisingly rare, this is a nice one ex Les Hitchings collection.
An excellent psuedomorph from Naica with bright, lustrous metallic gold and silver hues. The condition is excellent and the esthetics are far better than most. These have occasionally been found in this famed mine, but never very many and none for some years.
