Balydonite -classic locale
stock #0040-JM-135
Penberthy Croft Mine, St. Hillary
Cornwall, England
8 x 6.7 x 4.7 CM (cabinet)
price: $750
Spring 2020

A colorful and attractive very old Balydonite specimen from Cornwall with rich density. Ex Lechner collection (Austria) a mid to late 19th century collection that had also absorbed several earlier collections. The collection was dispursed in 1940-50 era. In 1969 sold to John Marshall via Schortmanns. This specimen is well over 100 years old, perhaps much older. The original label does not specify the mine but with the Lechner collection number (7132-13-23) it can be confirmed that this is in a sequence from the famed Penberthy Croft, and the habit etc is a perfect match for this location, which is also the type locality. The mine closed in 1840. There are several other species present that are not identified but what appears to be an area of Cornubite is noted as is some areas where the Balydonite has partly covered by a bluish-white mineral. Overall a choice classic example that has several possible display angles. Labels from Schortmann and Marshall are included.
SOLD Astrophyllite- rare Northeastern USA
stock #SOLD 20.1-166
Hurricane Mountain, North Conway, Carroll County
New Hampshire, United States
3.7 x 1.6 x .5 CM (small miniature/ large thumbnail (toenail))
price: $0
Spring 2020

A remarkable cluster of Astrophyllite crystals that at some angles looks almost like Brookite mass. No matrix and with a good brassy iridescent luster, this is the best example I have ever seen from the Northeastern USA, and very fine from anyplace. Collected by Les Hitchings sometime in the 60's on Hurricane Mountain, this is very unlike typical specimens that are more micacous or fibrous and lay flat on encasing matrix. Some references list Astropyllite as a "very rare" Potassium, Iron, Titanium Silicate mineral, but in recent years there have been many specimens from the Khibiny Massif coming out, so this is no longer such a rare specie. However, well defined crystals are still rare and this is a very choice example. The ends have some bruises or contacts but overall this is fantastic for a USA specimen.
Kyanite -gemmy crystals on Quartz
stock #16.1-630
Capelinha, Jequitinhouha Valley
Minas Gerais, Brazil
6.7 x 3.8 x 3.3 CM (cabinet)
price: $750
Spring 2020

This is not at all a typical Kyanite, the crystals are vivid blue, gem clear and are sharply terminated. Well presented on a massive Quartz matrix, these crystals are perfectly exposed and brilliant in person. With backlighting this glows an intense blue hue. Some zoning is noted with the "stripes" of clear and deep blue running along the C axis of the crystals. Huge amounts of Kyanite come out of Brazil but super gem grade display pieces are very rare, this is a superb example with a lot of display impact. Better in person.
Rose Quartz (classic style, Maine)
stock #13.1-399
Dunton Quarry, Newry, Oxford County
Maine, United States
3.1 x 2.2 x 1.7 CM (thumbnail)
price: $320
Spring 2020

A super choice thumbnail (just barely fits the specs) with fine form, color and luster. From Newry, the Rose Quartz is in ball like clusters and seems to have formed on an earlier colorless Quartz druse. Looks fine from several angles, the condition is excellent, undamaged. While massive Rose Quartz is rather common, it is surprising how few good crystalized R Q specimens are found worldwide, most finds seem to be very small.
Almandine - important specimen from classic locale
stock #0944-JM-M19
Mount Mica, Paris, Oxford County
Maine, United States
6.1 x 5.3 x 3.8 CM (cabinet)
price: $390


An important and choice Almandine on pegmatite matrix from the 1974 Dagenais Pocket (named for Rene Dagenais). This specimen was in the collection of John Marshall who was at that time one of the owners of the locality. According to John it was the best Garnet he had seen from Mt Mica. The specimen retains his painted on label and collection number M-19. The Almandine is mostly complete with dark red higlights. There is an area of damage on the backside but the front is clean and presents well. Garnet is rather common at the famed Mt Mica, but any well formed crystals are especially rare. A significant specimen from a famed pocket and important for the locality.
Aragonite -zoned crystals on matrix, Type locality
stock #18-AX-10-668
Molina de Aragon
Castile-la Mancha, Spain
4.5 x 3.6 x 2.3 CM (miniature)
price: $230
Spring 2020

Aragonite crystals with a violet core perched on matrix from the type locality in Aragon, Spain. Matrix crystals from this prolific locality are incredibly rare and the purple zones are the most desirable. The matrix is quite fragile which helps to explain why most specimens are single loose crystals. An older specimen from the Ara Dildilion collection with original label.
Fluorite on Quartz
stock #18-AX-18-019
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
9.3 x 4.8 x 3 CM (cabinet)
price: $260
Spring 2020

An unusual etched gemmy cube of Fluorite is perched on a clean white crystalized Quartz matrix. Overall in fine condition as seen, the Fluorite has a hopper-like form with complex structure best seen in person or under magnification. A large amount of fine Fluorite has come from Yaoganxian over the years but this habit is very unusual. Strong blue color and high luster make this a nice choice.
HOLD Langbanite crystals with Fl. Rhodonite
stock #HOLD 066-JM-2935
Langban (Langbanshyttan)
Varmland, Sweden
8.4 x 6.2 x 4.3 CM (cabinet)
price: $340
Spring 2020

A complex specimen from the famed Langban locality with several species well represented. This features several large areas black Langbanite with some sharp crystals to several MM in size. Also nestled in a shallow vug are blocky crystals of pink Rhodonite that are vividly Fluorescent. Most Rhodonite worldwide is not at all fluorescent but this has intense red to orange red response in long wave. This Langbanite is of course from the type locality, it is a quite rare Manganese Silicate specie and not very often available. Ex John Marshall collection, his label is included.
