Cubanite twin crystals in a cluster with virtually no matrix. In fine condition as seen, such good Cubanite crystals have become quite rare as it has been over two decades since the last of this world class find. This one shows excellent golden luster and form, the largest crystal is a full sixling twin. It is very unlikely there will ever be more of this quality found. There are several localities in the world for this mineral but any crystals are very rare and almost all are micros. These Canadian specimens are the by a wide margin the best in the world, and good twins are especially scarce now.

Mina Ojuela, Mapimi
4 x 2.8 x 1.3 CM (miniature)
new year 2021
Miniature specimen densely covered with bright, glassy crystals of Paradamite. A choice piece of this highly desired rare species from Ojuela. This specimen has been in the J.A. Dague, Dr. Herman March and the Terry Szenics collections. In fine condition, the crystals are very sharp and gem clear. Older specimen from the early find, the matrix is typical gossan but stable and solid without any crumbling.
Digenite with Pyrite and Quartz
Leonard Mine, Butte, Silver Bow County
7.7 x 6.1 x 3.8 CM (cabinet)
new year 2021
A choice and classic Butte specimen of Digenite crystals on a contrasting matrix. Normally Digenite is an unattractive sooty black rarity, loved only by serious Sulphide lovers (like us). This specimen is very much nicer, and actually displays well. These crystals are quite good sized, and are well set on a sparkling bright contrasting matrix. The crystals of Digenite are usually rather crude and these are too, but still have a distinct form showing structure. The largest crystal is about 1.5 CM across. Contrasts well with the sharp and bright golden Pyrite. In excellent condition, this is ex John Marshall Collection with his collection card. He obtained this in 1979 from A.L McGuinness and that label is also included.
Fluorapatite with Elbaite
Pederneira Mine, Sao Jose da Safira, Doce Valley
6.3 x 4.3 x 4.7 CM (cabinet)
new year 2021
A very fine, super colorful and very unusual Apatite from the famed Pederneira Mine. The Apatite crystals show several generations of growth and color zoning quite different from the tourmaline the mine is famed for. This specimen also has a bi-colored, doubly terminated Elbaite crystal on the backside that is 4.7 CM long, a nice addition. The Apatites have sharp flat terminations and colors zones in purple, blue, orange-red and some dark green. These also show well some selective growth and etching with areas of re-crystallization. This makes for a complex and especially interesting presentation that looks fine from several angles. Excellent condition with no damage, this is the best Apatite I have seen from Pederneira, and would be a fine piece from anyplace. Vividly fluorescent with a zoned responses corresponding with the daylight color areas.
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.
