Topaz -Rare purple
stock #19.1-806
Ouro Preto
Minas Gerais, Brazil
2 x .9 x .7 CM (thumbnail)
price: $1150
Spring 2020

Gemmy thumbnail crystal of imperial Topaz with the very rare pink-purple color. From the classic locality of Ouro Preto which has produced vast amounts of yellow and light orange Topaz over many decades. The purple and pink-purple colors are unique in the world. At Ouro Preto these are very rare and highly sought after, there has not been any new finds of purples in many years. Some similarity is seen with pink Topaz from Katlang, the only other source that ever came close, but the purple color from Ouro Preto is quite different, and treasured as gem rough and especially as specimens. This crystal is fully transparent, complete and lustrous.
Hydroxlherderite
stock #15.1-152
Tamminen Mine (Quarry), Greenwood, Oxford County
Maine, United States
2 x 1.6 x 1.4 CM (thumbnail)
price: $90
Spring 2020

A thumbnail cluster of Hydroxylherderite crystals up to 1.6 CM in size. This specimen was collected in the mid sixties by Les Hitchings. The Waisanen Quarry is part of the legendary Oxford County, Maine pegmatite zone and is well known to local collectors but less so farther afield. The quarry has yielded some many rare minerals, many Phosphates and and occasional gem crystal but is best known for the Herderites. A nice thumbnail, these are not often available.
Silver -classic thick wire
stock #20.1-100
Kongsberg Silver mining district, Kongsberg
Buskerud, Norway
2.5 x 1.5 x 1 CM (thumbnail)
price: $950
Spring 2020

A stout, well formed Silver wire in ramshorn form from Kongsberg. For some reason, Kongsberg Silvers tend to be thicker, rope-like wires of this sort, the form is unlike most other localities. A killer thumbnail that looks fine from any side, ex Mario Pauwels collection. Kongsberg is of course a legendary Silver locality, which started in 1623 and peaked in the 1770 era. Long closed now but this region produced incredible quantities of Silver for centuries. Some huge wires were found long ago as thick as an arm. those are now priceless treasures seen in museums only. This much smaller piece is like a perfect scaled down version of those famed fat ropes of Silver.
Childrenite- Eosphorite (gemmy with unusual color)
stock #19.1-805
Mendez Pimentel
Minas Gerais, Brazil
2.6 x 1.8 x .9 CM (thumbnail)
price: $390
Spring 2020

A super single crystal thumbnail of red-orange Childrenite ex John Buckley Collection. This is translucent to transparent and has internal zoning. From a find many years ago at Mendes Pimental, there were very few found with this unusual color, it is possibly closer to the Eosphorite end of the series though the original testing called this Childrenite, we have not re analyzed this. Complete and well terminated, one part of the termination hosts a zone of tiny doubly terminated Quartz crystals which adds a nice contrast. No matter the specie this is a choice colorful example of both ends of the series.
Witherite on Fluorite
stock #20.1-083
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
2.8 x 2.6 x 1.8 CM (thumbnail)
price: $140
Spring 2020

A complete ivory colored Witherite crystal sitting on a blue crystalline Fluorite showing classic form. From the famed Minerva #1 Mine, this is a well formed thumbnail specimen in very good condition. The faces of the Witherite have the characteristic tiny stepped structures that are so definitive for this locality.
Pyrochroite- unusually large, sharp crystals
stock #18-AX-14-388
Kalahari Mn Fields
Northern Cape Province, South Africa
2 x 1.7 x 1.3 CM (thumbnail)
price: $290
Spring 2020

A fine well crystalized example of this rare and usually unattractive specie. From the Scalisi collection, there are just not many of these in existence, this has large somewhat etched and crude crystals with a few tiny rough spots seen with magnification. With very strong (40X) magnification some very tiny Rhodochrosite rosettes and what seems to be Shigaite are spotted. The largest crystal is 1.6 CM across . The habit of this piece on one side looks like the type from Franklin NJ, but the other side looks from the Kalaharie Mn fields. Not a beautiful mineral to most people, but a good example and very hard to find
Adamite- Manganoan (purple) with Austinite
stock #19.1-752
Mina Ojuela, Mapimi
Durango, Mexico
2.8 x 2.2 x 2 CM (thumbnail)
price: $700


Killer thumbnail with intense bright color and great esthetics. A cluster of Adamite crystals showing saturated color zoning and featuring a saturated Purple sector. In perfect, undamaged condition. The back side and a few other spots have some nice small balls of Austinite as well, an unusual combination that adds a bit to the overall interest. Purple Adamite from Mina Ojuela is one of the most desired of Mexican minerals, this color and quality is found rarely and prized.
Wulfenite "windowpane" type
stock #19.1-994
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
1.8 x 1.6 x 1 CM (thumbnail)
price: $160


A smaller thumbnail that has a super presentation. Two main Wulfenite windows are nicely perched on a sliver of crystalized Calcite matrix. Very tiny balls of red Mimetite add color so that at certain angles the Wulfenites are a more reddish or yellow depending on the perspective. In fine condition as seen, this looks great from several angles. The Rowley mine tended to have smaller and more delicate Wulfenites but they could be incredibly esthetic. A choice little piece with more display impact than might be expected.
