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
stock #AC 204
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.
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.
Lahn Valley, Rhineland-Palatinate,
4.2 x 2.5 CM (miniature)
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.
Tantara Mine, Shinkolobwe, Central Area
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 and superb gemmy scepter crystal with internal movable bubbles. The head is glass clear, with light smokey color, and razor sharp. This also has milky white stem for contrast and overall in in super shape. For the size (4 " tall) it is remarkable to have such clarity and condition. We have seen and sold a lot of fine Cong Ly quartz but this ranks as a top piece for this locale and a very fine scepter for anyplace! We originally sold this piece and it has returned in a trade deal, it was obtained on our Fall 2002 trip to China, we have not been able to get any material of this quality for the past 3 years.
A large, heavy mass that's nearly all silver minerals, this is a rich specimen covered with the ropey 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.
A very attractive light lilac/ violet gem crystal of Scapolite from this important locality. This is actually 2 crystals grown together with the terminations staggered and showing great glasslike luster. No damage by naked eye but with 10X magnification there are some very tiny contacts and a very insignificant chip that need to be mentioned. A very nice example of a mineral that is usually quite nondescript!
