A fantastic blue cap Tourmaline . The main crystal with four distinct bright colors dominates this esthetic miniature. The smaller side crystal is also a blue cap with three colors and a large percentage of bright pink. In perfect, undamaged condition, when examined under good magnification even more color zones can be seen as faint areas between the main parts. From Stak Nala which is one of the world's best localities for fine Tourmaline. From time to time some exotic and uncommon color combinations like this are found there. The dark area in the middle is actually a dark green when backlit with strong illumination. A fine addition to any suite of gem crystals or tourmaline collection.
Wulfenite on Dolomite
2.3 x 1.8 x 1.6 CM (thumbnail)
new year 2021
Wulfenite in isolated crystals are nicely perched in tiny Dolomite crystals. The Wulfenite habit is the beveled edge type with a lustrous orange color. A choice thumbnail from the William Severance collection (his label is included). Bill has always had excellent taste and high standards for esthetics, and this piece shows that good taste well. Tsumeb has been the source of many forms of Wulfenite but this particular style, color, habit and overall look is unique to Tsumeb and instantly recognizable.
A single flat elongated Chrysoberyl crystal just over 2 CM long is embedded in a complex Pegmatite matrix. The Chrysoberyl is rather crude but it is terminated and under magnification is translucent with small areas of transparency. This specimen is from the Greenfield NY locality that now seems to be lost, but many years ago produced several Chrysoberyl in different habits. This is not a pretty specimen to most people but the habit is unusual and these are quite rare in any form. There seems also to be some areas of alteration on some faces, and the entire matrix show evidence of a complex mineralogy with several other sorts of alterations. Ex W. Hladysz and R and A Palmer collections, a nice piece for a serious Northeastern USA suite.
SOLD Spessartine on Gem Aquamarine
stock #SOLD 18.1-770
Dassu, Braldu Valley, Skardu District
Gilgit, Northern Areas,
4.5 x 1.6 x 1.4 CM (miniature)
new year 2021
Fantastic contrast with bright red Spessartine Garnets on and inside a very clear Beryl (Aquamarine) crystal. In exceptional condition the Aquamarine has several faces showing negative imprints in the shape of Garnets that are no longer attached. The Spessartine is translucent to fully transparent and the Beryl is a fine blue gem grade with a few wispy inclusions and some complete small Garnets. This piece was found in one significant pocket in 2018. Far more striking in person, the Beryl is perfectly transparent and clear when viewed down the C axis.
Brazilianite with Cleavelandite
Telirio Claim, Linopolis, Divino das Laranjeiras, Doce Valley
5.7 x 5.4 x 3.7 CM (cabinet)
new year 2021
Large, textbook perfect and lustrous Brazilianite from the find in 2009 at Telirio. This is a cluster of fine, green to yellow colored Brazilianites with the largest crystal 4.5 CM tall and relatively thick. The condition is perfect and the specimen can display well from several angles. Most pieces of this find were the more common slender habit but there were a few that had this fatter form looking more like the very early finds decades ago. This piece has that form and the crystals are all fully transparent. In person the color is a bit more vivid and with super glassy luster. Sourced in Brazil at the time of the find from the late Dr. Luis Menezes. Luis was an amazing mineralogist and the man responsible for many of the greatest Brazilian specimens for decades.
Small, perfect, complete and with fine orange color, a bright Wulfenite from the Rowley Mine. The windowpane form is super sharp and fully transparent, there is a little Mimetite on the bottom and some Calcite on the back but overall this is just Wulfenite. Perfection is quite rare with these delicate crystals but there is no damage or chipping seen. Even though this is a smaller thumbnail the color and luster give this a good display pop.
Lanarkite with minor Cerussite
C and B Mine, Christmas, Banner Mining District, Gila County
4.6 x 4 x 2.7 M (miniature)
new year 2021
Not a pretty specimen but ultra rare, a confirmed Arizona Lanarkite. This blocky matrix holds two small zones of Lanarkite and a few scattered very tiny Cerussite crystals. The largest bit is clearly eye visible (though still small) greenish yellow and 4mm across. This Lead secondary specimen comes from a small long closed polymetallic mine that has yielded very few other pieces, mostly all being micros. An uncommon mineral that is especially rare in the USA, this Lanarkite is not clearly crystalized mostly in platy cleaved masses. One very tiny spiky form crystal is seen only with very high power magnification. A very hard to get addition for any comprehensive Arizona suite.
Kayenta, Navajo County
2.8 x 2.2 x 1.4 CM (thumbnail)
new year 2021
Colorful thumbnail of this uncommon Copper-Vanadium specie from Arizona. This specie was known as Calcio-Volborthite for many years but is now renamed Tangeite after this was re-described from an older type locale in Kyrgyzstan. Well-formed crystals on contrasting matrix that are especially vivid under the microscope. This mining area close to Monument Valley has several small old workings which were sources as far back as the late 19th century.
