Fall 22
An exceptional Euclase from Piaotang (China) from the one time find in 2007. In excellent condition, no naked eye visible damage. The crystals are up to 1.4 CM though most are 1 CM or smaller. These are all water clear, gemmy, well-striated and very sharp. There is a silvery sheen reflected from lustrous faces much like an Apophyllite. The habit of the crystals is similar to older Brazilian specimens, but they are also distinctly different on close exam. This specimen is from Dr Marcus Lueg collection and stands as one of the very best of the find.
A very well-crystallized classic specimen from the ancient mining district of Pribram. The silver-rich Tetrahedrites had been called Freibergite but this is now a discredited specie name but exists as a subgroup tin the Tetrahedrite family. This is a superb piece with well-defined crystals on sizable Siderite crystals. The cluster of Freibergite/Tetrahedrite crystals is 3.2 CM across and is overall in good condition though there are some bruises to mention. despite that this is still a killer for the locality and specie. Silver was chased in this zone going back for centuries, later lead and finally Uranium were sought. Silver species are quite prized and well-crystalized specimens are now rare from this famed mine.
Adamite - classic Mexican
stock #16.1-147
Mina Ojuela, Mapimi
Durango,
Mexico
6.3 x 4.7 x 4.6 CM (cabinet)
price: $950
Fall 22
A killer hemisphere of green Adamite crystals resting on a second generation of red-brown Adamite and Calcite. An older piece from Mina Ojuela which has produced so many great Adamites in a wide array of forms. One of the most sought after is the compound ball or hemisphere form. This ball is large (almost 4 CM across) with fine luster as seen. One side shows the rounded faces of the cluster of Adamite crystals that form the ball. The opposite side is completely different, it is concave to flattish with a rim of sharper more defined prismatic crystal that have extra bright luster. The Matrix is the usual gossan but well covered with sharp Adamite crystals that seem to be included by some of the Hematite giving a reddish color. The ball itself is vividly fluorescent and all is in fine condition.
Super esthetic, a brilliant and rich Rosasite specimen from the famed Mina Ojuela. An outstanding example of this colorful Copper specie. A thumb-like projection of matrix extends out of an open cavity and is thickly decorated with blue-green balls of Rosasite and sheaves of clear Hemimorphite blades with sparkling small Calcite crystals. In perfect condition the vivid color and bright luster are top shelf. Most Mina Ojuela (and other localities) Rosasites are velvety to dull in luster. This piece with the addition of the Calcite next to and on top of some Rosasites is extra bright and eye-catching in person. The matrix gives a fine contrast.
Calaverite - classic USA Gold
stock #22.1-441
Cripple Creek District, Teller County
Colorado,
United States
6.7 x 6 x 4.1 CM (cabinet)
price: $750
Fall 22
A sizable matrix specimen of very rich Calaverite and some very small areas of Gold on a matrix of Chalcedony and Calcite. This type of matrix is usually considered to be from the third and final Mineralizing event at this locality, the earlier events often had considerable Fluorite instead. This piece shows several areas of distinct crystals many of which are complexly twinned. Some of these are fairly complete but others are contacted or broken which is very typical of this fragile Gold Telluride. This area was one of the greatest Gold discoveries in the USA but was very unusual due to the many zones of rare Telluride minerals and Gold Tellurites in particular. This is an excellent large and rich example.
A large, well-formed Apatite crystal with a garden-like growth of Actinolite crystals inside. In excellent condition as seen, the color is a deep oil green on the lower sector and is more clear light green at the top. This is a classic style of Alpine Apatite yet comes from the Himalaya region. The large flat glassy faces are partly composed of stepped flat hexagonal planes. A choice and attractive crystal.
A remarkable and rare habit of Fluorite, this from the Orange River area of South Africa. The larger Fluorite crystals on this specimen are hexagonal stacks of flat crystals which on close examination are seen to be flattened spinel twins with small square edge windows. A second generation of bright yellow Fluorite is encrusting some edges of the blue to purple large Fluorites. Such unusual forms and habits make Fluorite an incredibly diverse example of the cubic crystal system. These are also prized as exotics by Fluorite collectors. In excellent condition on the front and sides, the back is both contacted and partly cleaved which is not visible from the display side. Especially for those who enjoy strange crystal habits this is a choice and attractive specimen.
Stibnite in and on Calcite
stock #22.1-543
Xikuangshan Sb Deposit, Lengshuijiang Co., Loudi Pref.
Hunan Province,
China
8.1 x 3.9 x 3 CM (cabinet)
price: $660
Fall 22
A super esthetic specimen from a remarkable find almost 15 years ago at Xikuangshan. This has a delicate transparent Calcite crystal perched on edge that is shot through with metallic Stibnite crystals most of which extend outside of the Calcite. This look great on all sides and the Calcite (3.7 CM across) is well-formed, complete and in fine condition. The black sparkling matrix is a very nice contrast to the metallic Stibnite and the Calcite. This specimen was in the collection of Michel Jouty, and is especially well-composed with a fine architecture.
