An very unusual older specimen from a find in the 1970's at Aracuai. The tourmaline crystal is both etched and prismatic with a large fibrous zone in the middle. The color zoning is unusual and includes the uncommon colorless (Achroite) variety. Ex Larry White collection, this is an attractive oddity and very different from other finds of fibrous Tourmalines. In good but not perfect condition, there is contacting and chips but not badly noticeable from some angles.

A big and well-crystallized Pyromorphite from a little known location, the Little Giant Mine. This specimen was in the famed Pyro suite of John Marshall, the best example from Little Giant he had been seen in his 60 years of Pyromorphite collecting. Later discoveries nearby at Bunker Hill mine are much more well known, but this locality had a few fine specimens before then. This is one of them and is if very good condition, has 2 generations of growth with crystals reaching 7mm densely covering the matrix.
A nicely composed, lustrous and sharp Romanian specimen from the classic Cavnic mines. Since this locality closed the unique habits of Cavnic Stibnites have become sought after. This is in very good condition overall, but for a perfectionist this is not perfect. Edge damage where this was removed is noted,magnification reveals more tiny chips and contacts elsewhere but most are less than a mm in size. Some rough looking terminations are not damaged but are the more hackly type nestled in with the prismatic ones. The main areas are mostly undamaged, and the most prominent crystals are fine. This displays well the rare flat-habit metallic Stibnites in an esthetic array on contrasting matrix. Affordable with nice form and reasonable shape for and older, delicate mineral.

A quite fine, sharp, lustrous, undamaged and well positioned Carrollite crystal on matrix. Good Carrollites have gotten hard to find. The great discoveries in the Congo were the best by far worldwide, but no fine pieces have come out in years, even damaged examples are scarce. This specimen though small has fine form with nice growth patterns on the faces. The crystal is 1.4 CM across.
Torbernite (old classic- type locale)

A fine, old German Torbernite from the Dr. Moritz Lechner collection (his number 7258 is attached). This important collection was begun in the 1850's and the number indicates this was likely added in about 1890. The collection was built from other significant old collections he purchased during those years, so this piece may be even older. The first descriptions of the mineral from here date to the 1770's. Ex John Marshall collection, this piece has a good relatively dense coverage of sharp plates with a nice deep green color. This locale is known for great Mimetites and some rarities, but it is also the type locality for Torbernite.
