Crystals of sharp, lustrous, complex galena cover a matrix of quartz and are associated here with the desirable brown, tranclucent siderite that is classic for this old historic locality. The galenas are typical Neudorf style, extremely lustrous with sharp terminal faces and complex sides, sometimes in elongated crystals, here to 4 cm. This MAJOR German galena specimen was purchased by a prominent German collector from American dealer Rick Smith in 1970. This was the same era in which he was trading many old specimens out of the American Museum collections, and in any case it is certainly from an old source as this habit and style is characteristic of the most sought-after Neudorf specimens, from the mid to late 1800s. Such large, robust specimens are very hard to find today on the market. They ONLY come from major old collections, and the occasional museum deaccession. The piece is in remarkable condition with only trivial and peripheral edge wear, and one area near the bottom of broken galena (although it may simply be contacting and not true damage there as parts of that irregular area look crystallized on a micro scale). Even so, I have seen few CABINET sized examples of any quality; and we regard this as a major specimen.

Seldom do you see old acanthites from this ancient district, isolated and on matrix. These relatively sharp crystals, to 1.2 cm in size, are really aesthetic, compared to most of the old acanthites we see from here. The matrix is 3-dimensional, and the piece is complete all around. It was in the noted collection of Arthur Montgomery, in the early 1900s. Recently, it was also in the noted classics collection of dealer/collector Larry Conklin. The crystals have a bright and natural patina and luster that is not the result of fancy chemistry to clean the piece, or whiten the siderite.Joe Budd Photos

Old french siderites are among the European "classics" that we hear about but seldom see. This sharp cluster has large crystals to several inches, a nice lustre, and really intrictate "swirling" form to the fat rhombohedra. They look as if in motion. This is an old piece, though no telling how old (I am told a nice pocket was found here in the late 1970s, though). The specimen was sold by dealer Herb Obodda into the first collection of Dr. Ed David by the mid 1990s, and retains his catalogue number 29T on the bottom. Speaking of which, this is actually a floater, crystallized all the way around, even (crudely) on the bottom. Overall very aesthetic and dramatic for a Siderite. Joe Budd photos

A cluster of gemmy, parallel-growth, colorless quartz crystals to 7.0 cm in length has grown on a matrix of smaller quartz crystals. Covering the matrix are bladed crystals of translucent, rosy-brown, siderite to .75 cm across. Nice color contrast and unusual overall for this locality! It is fully terminated, and a thin hematite crystal is included in the back , visible in looking through the crystal tip on the right. It is just a darned good Brazilian quartz, by any standard...how often do you see upright clear quartz crystals of this size perched up on any matrix other than more quartz!? Complete all around the front and sides, contacted only on the back. This piece is particularly significant for the locality. Comes with custom lucite base for display.

Superbly defined rhombs of Siderite that are actually two pairs of penetration twins. The luster is excellent, and the habits and geometry are just about as perfect as you can get. The edges even grade to translucent, which adds to the aesthetic appeal. There is some minor edge wear in one spot, but it is insignificant compared to the overall quality of the piece. Certainly one of the finest Siderites that I have seen.
