A flat Limestone slab with fine, well detailed dendrites on both sides. From the limestone Quarry at Eichstatt in Bavaria, this old locality is famed for Jurassic age fossils but also for excellent dendrites. from the Les Hitchings collection, obtained in 1987 the slab is sawn on 4 edges but rough natural on the faces. The original label for this refers to the dendrites being Pyrolusite but in fact this is wrong, it is not uncommon for these to be composed of other Manganese oxides, sometimes a mix of species such as Coronadite, Birnessite, Romancheite etc. No matter the specie (which is complex to determine) this is a very attractive, delicate and highly detailed display of branching dendrites much like an artist's rendering.
Several Quartz crystals are clustered around a single gemmy Topaz crystal set on Clevelandite. The Topaz has some lightly frosted faces and others are glass clear, transparent and very lustrous. The color is a light sherry hue that looks slightly pinkish in some light. From finds in 2004 in Yunnan Province in China, we have not seen such good pegmatite minerals from this region for several years. In good condition overall as seen there is a crack in the Topaz and a chip is noted on one face that is not very evident or distracting. A really choice Chinese Topaz.
Azurite with Malachite
Touissit, Touissit-Bou Beker Dist., Jerada Province
3.9 x 3 x 1.7 CM (miniature)
Perfect prismatic Azurite crystals, the largest 2.8 CM long and doubly terminated. All are composed on an esthetic cluster on a matrix of small Malachite crystals. This is a 360 degree specimen, it displays well from most any angle. The Azurite is also translucent on the edges and, overall, the form and luster are excellent. Ex Charles M. Noll and Jimmie DuFoe collections, this dates back to the "golden age" of the Touissit Mines, which are still famed as one of the greatest Azurite localities of all time. Previous labels are included.
A cute single crystal of Indicolite Tourmaline studded with several clusters of Lepidolite. Under most lighting this is quite dark and looks almost black but with strong lighting the transparent blue is very evident. The termination is incomplete being contacted, the upper area is a more violet than blue. A nice example of 6.6 grams that is priced well below the market rate for gem Elbaite of this color.
Sparkling blue-green masses of Chrysocolla that has replaced earlier primary Malachite crystals. The entire surface is covered with tiny Quartz crystals that gives the drusy sparkle effect. Some very small bits of Malachite are still present but mostly this is all Chrysocolla. Some of the forms are fingers or stalactites in clusters, one of which has the look of a tree from the right angle. In excellent condition the color and form on this piece is outstanding. This locality has not produced any Chrysocolla for several years now. These replacements are a modern classic and in person this one is highly esthetic, far better than typical.
SOLD Linarite on Barite
stock #SOLD 20.1-630
Blanchard Mine, Bingham, Hansonburg District, Socorro County
5.5 x 4.5 x 1.5 CM (cabinet)
Dense cluster of electric blue Linarite crystals laying on a Barite and Quartz matrix. A classic USA locality, the Blanchard Mine was one of the world's best sources of Linarite. This is a nice example, with unusually rich coverage and with crystals to almost 2 CM in an intergrown mass. Collected by Les Hitchings in 1967, the striations on the long Linarite crystals have a bright wet look luster and are highly reflective.
A fine Yaogangxian multi-specie specimen hosting a prominent Siderite crystal perched on sparkling purple Fluorites. In excellent condition, we do not see much good Siderite from this famed locale that is better known for world class Fluorites and Sulfides. There are small crystals of several other species present as well as is typical from this locality, a comprehensive label can get quite long! Ex Shields and Frances Flynn collection, an excellent example of the specie from this iconic locale.
Amethyst - Grape Chalcedony/Agate
Manakarra, Mumuju area, Sulawesi Barat Province
6.3 x 5.7 x 2.7 CM (cabinet)
One of the most exciting and attractive finds of the past few years were these "Grape Agates" or Chalcedony spheres from Sulawesi. Now more correctly called botryoidal Amethyst, this material is unique in the mineral world and can be incredibly attractive. This is a select piece, well-formed on all sides with the desirable bicolor (green and purple) areas. The color on this piece is a good deep grape purple and the "front" is also covered with drusy Quartz that adds the most desired sparkling luster. In fine condition as seen, better specimens from this find are among the best values on the mineral market today, however recent mining has not been producing much of the higher quality.
