Bright blue and very well exposed on contrasting matrix, this is a striking specimen. In fine condition the form is complete with edge modification clearly visible, and just under 3 CM across. Typically the faces of these crystals are never very lustrous and can be fairly rough or crude. This specimen is about as lustrous as these get, the crystal faces show some course texture but are way more smooth than is normal. From finds a few years ago, a very attractive and clean piece.
Rutile on Hematite
3.6 x 3.4 x .2 CM (miniature)
Epitaxial arrangement of Rutile needles in the six ray form that is famous from this locality in Bahia, Brazil. A choice small example of metallic silver-black Hematite crystals with typical very flat habit hosting radiating needles of Rutile. Close exam of the Hematite faces shows complex striations and some embedded Rutile.
Rapid Creek, Dawson Mining District
4.6 x 3.2 x2.3 CM (miniature)
Superb, larger sized Augelite crystals of top quality in an esthetic cluster. Killer condition (no damage) and with the largest crystal 1.6 CM. Augelite is a rather rare Phosphate only found in such fine crystals like this from two localities worldwide. This specimen is exceptional for the Rapid Creek finds and has fine zoning, sharp, lustrous faces, nice color and some gemmy areas. This remote area of the Yukon has been a world class source of fine Phosphate specimens. The Augelites from here are distinctly different from the the newer finds at Mundo Nuevo (Peru).
Grossular -Gemmy crystals
Jeffrey Mine, Asbestos
3.1 x 2.1 1.3 CM (small miniature/ large thumbnail (toenail))
A cluster or stack of very lustrous Garnets with the classic color and form that made the Jeffrey Mine world famous. This is the flattened type of cluster with no matrix, it is entirely contacted on the back as was the case with this style, fully translucent and mostly transparent. This type of specimen was sometimes used as a sort of natural jewelry, mounted or wire wrapped as is or with the back ground flat. A very good value these Garnets show characteristic striations and growth hillocks. A fine modern classic from a source that will never again produce anything.
Mina Ojuela, Mapimi
5.7 x 4.6 x 1.9 CM (cabinet)
Adamite crystals standing up from the limonite matrix in both white and light mint green colors. Early seventies vintage specimen from Mina Ojuela, ex Les Hitchings collection. Vivid fluorescence and in excellent condition. A few Calcite crystals are also on the matrix but this is mostly all Adamite. So much good Adamite came out during that period in many habits that these were under respected. Currently much less is coming out and we know this was a golden age for the worlds best examples of this specie. Choice display with good visual impact for the size.
Heights Mine, Durham, Weardale County
4.1 x 3.3 x 3.3 CM (miniature)
Perfect and well composed Fluorite from the Heights mine. This cute miniature has a prominent, well isolated and very sharp cube perched on top. The edges and corners are sharp and perfect on this, the luster is glasslike and the Fluorites are quite transparent. No visible damage. A good value for a small, choice classic British Fluorite with a quality well beyond typical.
Quartz on Chrysocolla and Malachite
Phelps Dodge Morenci Mine, Morenci, Copper Mt. Mining District, Greenlee
11.6 x 8.1 x 6.2 CM (cabinet)
A large colorful Copper secondary display specimen from an old find in Arizona. A druze of tiny clear Quartz crystals is covering many green Malachite balls and areas of bright blue Chrysocolla. The overall effect is sparkling and vivid in person. A sizable specimen from Morenci. The bulk of the matrix is layers of Chrysocolla in several shades of blue looking like a rich Turquoise. Some of those thin layers seem to be "gem Silica" that when thick enough is highly sought after for Lapidary. These layers are too thin for that and the surrounding Chrysocolla is quite brittle besides. The matrix has been properly stabilized to keep it from cracking as some Chrysocolla can do. This piece is early sixties vintage and simply eyecatching.
Fluorite with phantom zoning
Okorusu Mine, Otjiwarango District
5.7 x 4.3 x 3.7 CM (small cabinet/large miniature)
Gemmy Fluorite cubes of blue-green color in a cluster on minimal matrix from Okorusu. This Fluorite has well defined inner phantoms of a darker violet-blue color and some cubes have a thin color zone extra near the outer edge. This specimen displays well from either side. The main crystals are prominent, sharp and clean, the only damage seen is minor on the outer edges where this was removed. Most Okorusu Fluorites are damaged, or the crystals are very tightly packed together, this is a nice exception. The mine has been inactive now for about three years and may be gone forever.
