Mimetite var. Campylite
Dry Gill Mine, Caldbeck Fells
4.9 x2.8 x 1.4 CM (miniature)
A cute miniature specimen with classic curved crystals of mustard-green Mimetite. The Mimetites contrast well with the matrix and have a good "wet" luster. From the famed Dry Gill locality that was at one time the most important source for the Campylite habit. These are now classics in the mineral world and this is an good value for textbook example of the curved barrel shaped crystals.
Malachite on Cuprite
Onganja Mine, Windhoek District
4.3 x 3.9 x 2.3 CM (miniature)
A modern classic, a sharp Cuprite octahedron is coated by a druse of crystalline Malachite, and rests on a contrasting Calcite matrix. The Cuprite crystal has very three dimensional relief from the crystallized Calcite background. Close exam of the matrix Calcite crystals shows many are included by bright red Cuprite and a few small bits of native Copper. The Malachite encrustations are a bit thicker and more sharply crystallized than the usual thin coatings. Onganja Cuprites are unique and are often quite expensive, matrix specimens are much less common. Choice and in fine condition.
An simply outstanding Mendip specimen with a large crystal lined cavity inside a Manganese Oxide mass. The void contains choice Cerussite and Hydrocerussite some in twins and others with reticulated forms, nestled on a sparkling Calcite. This Quarry is famed for the rare Lead minerals that are found here in association with the Manganese deposits in the Carboniferous Limestones. The location is unique and has been the source of at least eight new minerals. That said most of the specimens are not often well crystallized or esthetic. This is an exception as the Lead minerals are well formed and make an attractive display contrasting inside the cavity. The Merehead Quarry now known as the Tor Works Quarry began to be noticed about 80 years ago and is a world class source of many other rare species.
Amethyst - scepter
Piedra Parada, Las Vigas
6 x 2.3 x 2.1 CM (cabinet)
A fine, sharp and richly colored scepter from the great discoveries at Piedra Parada in Veracruz. This piece was in the Larry White Collection and retains his handmade wooden base. The termination has some skeletal or hoppered faces and some smooth faces. From most angles this looks perfect by naked eye but magnification shows some very small chips. Despite that this is far better condition and form than is typical for the locality.
Berg Aukus, Grootfontein District
3.6 x 2.8 x 2.3 CM (miniature)
A superb, perfectly crystallized Descloisite from Berg Aukus. This Namibian locale is famed for the very best Descloisites ever found. This is a small miniature with bright lustrous crystals with a dark red-brown color and translucent on the edges. Descloisite is a delicate mineral and perfect, undamaged pieces are rare,but this is one such pristine specimen.
Cornetite with Malachite
L Etoile du Congo Mine, Lubumbashi
Democratic Republic of Congo (Zaire)
7.2 x 4.7 x 2.3 CM (cabinet)
A powder blue crust of tiny Cornetite crystals mixed with some Malachite on matrix. This is sawn on the back but the front is all natural. An affordable example of this rather rare Copper mineral.
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.
Oberwolfach, Wolfach, Black Forest
6.9 x 5.4 x 4.4 CM (cabinet)
A classic Black Forest German Barite with well-defined chisel habit crystals. The largest individual is over 4.5 CM long, and all of them show a color zoning. The outer edges are a light blue while the cores are a very pale yellow with some red. Ex Charles M Noll collection, the luster is a frosty or satin gloss and very sharp definition. A choice older specimen that displays well.
