Goethite Xls on twisted quartz (gwindel-like)
stock #AC-128
Florissant, Teller county
Colorado, United States
13 x 7.5 x 4 CM (cabinet)
price: $200


Is this a Colorado Gwindel? A radiating ball of goethite crystals sits on a single flattened quartz crystal composed of several parellel growths that have a pronounced twist . The form is "gwindel like" but as the back side is less twisted I am not certain if this can be classified as one. I have asked some quartz experts and they are divided mostly because the crystal tappers to a wedge like form and is thus not fully typical. Whatever it can be classified as, it is unusual and a Colorado classic locality piece. This was broken and repaired many years ago (it was in a collection by the 1930's) and it is visible on both sides (more so in the back). There is some chipping and damage to the geothites, but it overall is in good condition.
Blue Spinel
stock #AC-259
Von Aoker
, Sweden
7x5.4 (cabinet)
price: $65


A sizable old location piece with a Dr. Krantz in Bonn label (a little different than most Krantz labels we have seen) there are several sharp octaherdral crystals etched from a calcite matrix. This is not a highly esthetic piece but it is a classic vintage and it does show the blue to purple octahedrons well.
Epidote on Byssolite
stock #AC 204
Knappenwand, Untersulzbachal Valley
Hohe Tauern Mts. Salzburg, Austria
7.2 x 4.8 CM (small cabinet/large miniature)
price: $45


From the historic and most highly regarded locality for Epidote this is a good example of the byssolite association and an inexpensive way to own a true classic! The Epidotes reach 1.5 CM set on a sparkling mound of Byssolite fibers. There is damage on the epidotes, they are not the gemmy crystals this locale is known for, but the Byssolite is very attractive. This piece is from a 1930's vintage collection and is very reasonably priced.
Smithsonite
stock #8.1-262
Kelly Mine, Magdelena district
New Mexico, United States
8.5 X 4.5 CM (cabinet)
price: $350


A very attractive and unusual crystalized smithsonite from this great American Classic locality. There is a rich crust showing discrete, rounded individual crystals with top quality color and luster on the gossan matrix. Good "wet" look to the crystals and a fine value for this very collectable locality. This is not the usual massive material and different from the "rice grain" type crystals.
Pyromorphite
stock #8.1-294
Bad Ems
Lahn Valley, Rhineland-Palatinate, Germany
4.2 x 2.5 CM (miniature)
price: $300


A fine, old, lusterous and esthetic pyro from one of the most classic locations of all, Bad Ems. This is also a classic form as it shows the stacked chain like growth of the individual crystals that flare to form a tree like structure. Good rich orange to dark salmon color and minimal damage that is clearly not distracting. These have been increasing in price and some quite damaged examples are currently on offer for far more than this piece.
Amazonite (microcline)
stock #7 COLO-502
Lake George, Park County
Colorado, United States
6.4x 5.5 CM (cabinet)
price: $350


A single crystal of the "white stripe" find showing excellent color and form. No damage (except on the base where it was removed) and just a tiny hint of matrix. This is a very good American classic locality and an esthetic crystal.
Fluorite (modified cubes)
stock #7 JF-115
Mina la Viesca, La Collada
Asturias, Spain
10.6 X 6 CM (cabinet)
price: $300


Fine and damage free cabinet of rich violet fluorites showing several types of modifications. Overall this is an attractive and clean piece and the main crystals are all pristine. There are some neat structures where the cubes have stacked geometrically. A super value on a very good Spanish Fluorite likely found about 1960.
Azurite
stock #7 AZ-117
Copper Queen Mine , Cochise county, Bisbee
Arizona, United States
10x10x 4.8 CM (cabinet)
price: $4000


A superb, classic locality piece with fantastic esthetics and rich color. This is essentially all Azurite with a tiny bit of malachite on the reverse side, and numerous micro crystals several of the classic species the locality is famous for. This specimen is composed of well crystallized Azurite in several habits up to 1 CM in size. This stands without aid and is very 3 dimensional. The condition is exceptional as this example is clearly very old, likely from the heyday of the mine in the later 1800's. Rare to find in this condition and quality !
