Sharp Fluorite with classic form of complexly stepped cubes (distinctive of some Asturias specimens) is the base for a spray of flat Barite crystals. Choice display specimen that is better in person, the Fluorite has a pale violet-blue color and a few purple phantoms. In fine condition damagewise, the delicate Barite blades are surprisingly all intact. Looks good from all sides this has no point of attachment it is fully crystallized on all faces. A remarkable specimen from all angles.
A very fine, old Pyro having two generations and two colors of crystal growth. A significant specimen, Ex John Marshall Pyromorphite collection, collected prior to 1900. John obtained this in 1972 at the Boylston Massachusetts Library auction of a collection originally donated in 1900. It took him a lot of research and trips to the British museum to clarify the locality. This is described on his detailed collection card included with the specimen. Nearly perfect, very little bruising as seen, most crystals are well defined and lustrous. A very choice example from a less well known classic locale.
Cuprite- gemmy red crystals
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
6 x 4.4 x 1.7 CM (cabinet)
Pre Holiday 2017
A well formed, bright stack of Cuprite crystals from the great Milpillas mine, better known for world class Azurites. This find of Cuprites created a big stir 2 years ago, but few were undamaged or had crystals much over a few millimeters. This piece is far better than average, in excellent condition damage wise and the crystals are stacked in an esthetic epitaxial arrangement. These octahedrons all will glow bright red with focused light passing through them, the photos here are only made with typical display lighting, so as not to be misleading. When these were first found the prices being charged were incredibly high, this is a lot more reasonable, yet a fine quality piece, by comparison a really good value.
A super thumbnail with a very sharp, lustrous Anatase estheticly perched on matrix. In fine condition as seen, there is one minor contact on a backside but no damage. Norwegian Anatase are some of the best in the world and are now classics. Choice.
Fluorite on Quartz with Calcite
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
10.7 x 6 x 4.4 CM (cabinet)
Pre Holiday 2017
An impressive Yaoganxian specimen with gem clear Zoned/ phantom Fluorites scattered on sizable clear Quartz crystals. Ex Charles Noll collection, an older specimen. Very 3-dimensional with top quality color and sharpness for the Fluorites. The backside and base of this are contacted and broken where it was removed which can not be seen on display. The display side is in impeccable undamaged condition which is rare. One of the worlds top mineral locales, Yaoganxian now produces almost nothing, this type of quality is only found in older collections.
An excellent Apatite crystal cluster from the older finds at the Sapo mine. Far better than most that came out, The color and luster and condition are first rate. These amazing but odd habit Apatites have had many names (Crullers, Snakes, Tubes, Medusas etc) and are fantastic examples of epitaxial growth; These have prisms in a chain or parallel growth that is built around a hollow tube composed of many stacked crystals. A really fine, textbook quality specimen in excellent condition. There is a separate smaller branch growth and very good transparency, color and luster on this. No damage or repairs which is rare in any piece of this size, this is even better in person, to me this is a real mineralogical marvel.
Wulfenite on Duftite
3.2 x 2.2 x 2.1 CM (thumbnail)
Pre Holiday 2017
A superb, sharp yellow Wulfenite crystal perched on a delicate matrix of bright green Duftite balls and related minerals. Great combination with wonderful color and in exceptional condition. With 20 x magnification I can just see one very microscopic bruise point that is impossible to find otherwise. Choice display specimen that has fine form and color contrast.
A complete, sharp transparent alpine style Apatite prism loaded with Byssolite needles that give the transparent colorless crystal a deep green hue. Very similar in form and look to Austrian and other European cleft Apatite. There is no damage and the whole is a floater with no point of attachment. Some of the edges show very complex multi faced crystallization and a few conjoined smaller crystals.
