Kelly Mine, Magdelena district
8.5 X 4.5 CM (cabinet)
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.
The mines of Madan have produce some wonderful and unique Galenas, this is one. The flattened spinel twins have been "melted" by later hydrothermal fluids and show several complex forms much like a jumble of flattened discoidal plates. The crystals reach 3 CM. This piece has a bright mirror like luster and is in perfect condition (except chips on one part of the outer edge where it was collected, and that is not easily seen) all the display face is undamaged and showey. I have enjoyed searching out some of the special Galenas from Madan this is a fine and different example.
Fluorite on Quartz
Xianghualing Mine, Linwu County, Chenzhou Pref.
10x 6.7 CM (cabinet)
The last thing the world needs is more green Fluorite from China, unless it is REALLY different! This is a different and interesting example of modified cubes that more like the material from Naica and older Dalnegorsk than China, they have the sharp and clear window face and are sizable at 3.4 CM. Nice mint green color and luster with color contrast on the matrix. Over all quite esthetic, tho there is noticeable damage on the periphery it still displays well. A good addition for a Fluorite suite, or a China collection as this is not typical!
A wonderful esthetic for a dark mineral like Bournonite is to be displayed on on colorful matix, and this piece does that well. Several sharp, prismatic and lustrous silvery crystals of Bournonite are well placed on a sparkling purple fluorite and quartz mixture. A few matted hairs of Boulangerite are in evidence as well. There is one Bournonite that is broken off (not very distracting tho) all the rest are quite clean by eye and only show some edge chips at 10X magnification. A very good matrix Yaoganxian piece and a good value.
Epidote on Byssolite
Knappenwand, Untersulzbachal Valley
Hohe Tauern Mts. Salzburg,
7.2 x 4.8 CM (small cabinet/large miniature)
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.
SOLD Blue Spinel
stock #SOLD AC-259
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.
Tantara Mine, Shinkolobwe, Kambove District
Democratic Republic of Congo (Zaire)
8.9 x 7 CM (cabinet)
An incredibly attractive mineral! Brilliant and lustrous crystals to 1.5CM with top color are packed in a vug that is rimmed with Dioptase and some blue Shattuckite. No damage to the display area and main crystals but there are a few tiny contacts at the outer edge of the piece that are not easilly seen. Really a killer for form and with bright, wet looking luster, this is a great value for the price. I have not seen anything of this quality in any recent lots from the DRC.
A large, heavy mass that's nearly all Silver minerals, this is a rich specimen covered with the ropy wires and radiating arrays of Kongsbergite and dull black Acanthite showing a few crystals but mostly in masses. Kongsbergite is a Mercury-rich Silver (only about 5% the rest is silver) it is relatively uncommon, and some of the wires here may be pure silver as well. There are only a few tiny bits of Quartz to be found on this otherwise it is an all silver specimen.
