A German classic specimen covered on all faces with very tiny crystals and crusts of Erythrite. This is the type locality for the mineral though it is not very common there. The underlying matrix is a heavy Cobalt rich mass that probably is Skutterudite or similar since some tiny cubic shapes can be made out under the crusts. A rich "Cobalt bloom" specimen that has some nice sparkle under strong lighting.
Duftite on Calcite
3.5 x 3.2 x 2.2 CM (small miniature/ large thumbnail (toenail))
new year 2021
Calcite rhombs in a jumbled cluster richly encrusted with Duftite some of which is the matrix for a second generation of tiny Calcites that add a lot of sparkle. Classic Tsumeb piece, in very good condition, the Duftite is in well-formed balls and looks especially bright under magnification.
Historic Meteorites with impressive provenance. From G.F. Kunz collection to Amherst college to Warren Johansson (in 1931). Three fragments of Iron meteorite total weight of 19.9 grams, the largest 2.6 CM across, these each have a distinctly different look, a very interesting suite. From the famed May 10th 1879 fall at Estherville, Iowa. Two of the pieces have had some areas ground revealing the bright metallic interior. This was a witnessed fall and was quite famed at that time. The historic details seen on line differ in many details (like this was a 744 pound mass or a 455 pound mass). All accounts do agree this was an exploding meteorite and a spectacular event. Verified fragments are quite rare and well valued.
An older, choice Benitoite specimen with several deep inky blue gem crystals contrasting with the matrix. There is certainly more good Benitotite within the Natrolite but as is this has a nice display. The color on several crystals is super. A few tiny transparent orange Joaquinite crystals are also seen on close exam. The old Schortmanns label for this piece gives a late 1940's vintage though this is possibly a pre-WW2 specimen. This is from the type locality for both Benitoite and Joaquinite. Top Benitoites have become incredibly expensive, this is not a top piece but it is not a four to six figure price either, a very good value for the quality.
SOLD Fluorite - zoned classic USA
stock #SOLD 15.1-036
Minerva #1 Mine, Cave-in-Rock, Hardin County
7.2 x 4.8 x 2.3 CM (cabinet)
new year 2021
A small cabinet specimen of Fluorite that is mostly yellow but with light blue and purple edges on selected crystals. Nice face structures and etching that is classic for the locale. No matrix except for Fluorite so the whole specimen is translucent and glows well with backlight. Overall in fine condition, there is almost no bruising, but under magnification some tiny bits are noted. Nearly every Fluorite from this region under close inspection has some sort of damage but this is far better than usual, and a relative great value.
Gem Sodalite on Calcite
Gem Sodalite Locale, Ladjuar Medam, Sar-e-Sang, Kokosha Valley Khash an
4.9 x 3.4 x 2.3 CM (miniature)
new year 2021
A single, partly gemmy, crystal of blue Sodalite sitting on a Calcite matrix. The Sodalite is vividly Fluorescent (yellow-orange) as is the Calcite. From the remarkable deposits at Sar-e-Sang, gem Sodalite is quite uncommon worldwide and the best by far are from this locale. A very nice piece with some very tiny rough spots that are only seen by magnification.
A sizable and very fine cabinet specimen of well-crystallized Brewsterite from the type area for the specie. Brewsterite is the less common analogue of Heulandite and can be Sr or Ba dominant. This specimen is almost certainly the Sr dominant version though not tested. This has hundreds of well-formed crystals which are transparent to translucent and very lustrous. Ex Hitchings collection this is an older specimen that was obtained in trade. Excellent undamaged condition.
A cute and colorful miniature from the great Mina Ojuela. Transparent Calcites are included by a fibrous Malachite and sit on a mixture of botryoidal Conichalcite and Malachite. This could be trimmed to a thumbnail size but this is very nice as is. In fine condition as seen, this is a very good example of an esthetic but affordable specimen, carefully selected from amongst a huge number of average level specimens.
