A significant and exceptionally fine cabinet specimen of well crystallized Olivenite-Zn from Tsumeb. The surface is densely covered with tabular hexagonal crystals which is a rare Olivenite habit typical of zinc rich varieties which is chemically very close to Cuprian Adamite. The crystals are clustered in rows, stacks, sheaves and rosettes. The condition is excellent and by naked eye perfect, 20X magnification finds just a few very tiny rub spots. The matrix is massive Cuprite and the esthetics, color and display quality are all top notch. This is an exceptional and important Tsumeb specimen that will be a fine addition for a top quality suite.
A finely crystallized Tsumeb specimen that has many twinned cogswheel form crystals well perched on the contrasting matrix. Treelike clusters of green Malachite are on the edges and the whole is quite three dimensional. Cerussite is a very delicate mineral usually with much chipping or other damage, these are in excellent condition even at 10X magnification. A good classic specimen.
From a one time find at the Jeffrey mine came some unusual gemmy pink Grossular garnets. This specimen is in fine condition, the main display face is undamaged, a few edge crystals have chips seen only with 10X magnification. This small display piece has bright glassy luster and good transparency on the crystals.
Jeffrey Mine, Asbestos
3.5 x 3 x 1.5 CM (miniature)
The Grossular Garnets of the Jeffrey Quarry are highly respected and desired. Top specimens can command huge sums. This small miniature is fine, gem clear with good color, form and condition yet is quite affordable. The crystals are gem clear and have super bright luster. A few small Pectolite crystals are seen on the back side as well. In excellent condition, at 10X magnification the Garnets are undamaged.
A nice, affordable Tsumeb Wulfenite showing sharp dark cognac colored crystals on a complex, contrasting matrix. Micro crystals of several species cover the matrix. The Wulfenites are translucent to transparent and have some tiny edge chipping as seen. Inexpensive for this classic locale due to the small imperfections, ex. Clive Queit, with his label.
A good, clean, classic Tsumeb Smithsonite that has fine esthetics. The crystals are fully translucent and have a slight zoning as well. These also have the iridescence inside the prisms that is distinctive for fine Tsumeb Smithsonite. In excellent condition damage wise, this is a very good value for such a well formed cabinet specimen.
A prized find for any classic USA collection is a good Royalston Aquamarine. This one is a small but super fine, gemmy and esthetic specimen. Collected by Warren Johansson in 1948 this was in his collection until his recent passing. Warren made finds at Royalston in 1937 and 1948. These were the last important specimens to be collected there. This locale was famed back in the 1850s, visited by Dana mined by Hamlin and others it is legendary. This piece is quite gemmy with the rare sought blue green hue. Despite a small chip the condition is excellent for the locale and this has great form with contrasting matrix. We have not seen any Royalston close to this good available for years
Brazilianite with Muscovite
Telirio Mine, Linopolis
5.1 x 3 x 2.2 CM (small cabinet/ large miniature)
Another Brazillian classic. This features a fine sharp, glassy and partly gemmy Brazilianite that is nicely paired with Muscovite showing twin crystal forms. In great condition, the specimen displays very well from several sides. From the major pockets found in 2008, this quality is not being found now. There have been two major finds of fine Brazilianite in the past 70 years, both were different in habit, it may be a long while before the next one if ever. A good value for an esthetic and choice specimen.
