Copper in and on Calcite USA Classic
stock #18-AX-12-460
Keweenaw Co.
Michigan, United States
5.3 x 3.4 x 2.7 CM (cabinet)
price: $1150
Spring 2020

An excellent vintage Copper in Calcite from the famed Philadelphia Academy collection, and retains their original label. This also has labels from Collectors Edge and Carter Rich, and was for a time in the William Hladysz collection. The matrix here is mostly clear Calcite in clusters of crystals more or less aligned. The clear Calcite are colored red-brown by large amounts of included copper easily seen inside the crystals. In several areas the Copper crystals extend outside the Calcite. The main crystal is 1.2 CM and very well formed. In excellent condition, and much better looking in person.
Sphalerite on Dolomite -Classic USA
stock #19.1-809
Pelican Mine, Picher, Tri-State District, Ottawa County
Missouri, United States
6.6 x 5.2 x 4.8 CM (cabinet)
price: $450
Spring 2020

An old Tri-state USA Sphalerite with complex twinned crystals in an intricate cluster. No damage at all, the Sphalerites are complete on all sides (which is rare) and have many distinct penetration notches and ridges. Super presentation and esthetics ex. John Buckley collection, this is far from being a "black ugly" the form is incredible.
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.
Fluorite -classic zoned crystals
stock #20.1-106
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
6.4 x 5.6 x 4.8 CM (cabinet)
price: $1750
Spring 2020

A super blue to yellow-orange zoned Fluorite with excellent form and outstanding surface modifications. A modern American classic, this is a choice display quality specimen that has a main cube presenting a textbook perfect inset in the largest face. Careful examination will find a few very small edge rough points, which are almost inevitable. Overall however this is in very choice condition. The backside is the former point of attachment and is contacted there but the front is well developed. With backlighting this really glows. Hard to find good Illinois Fluorite of this color now except at very high prices. A good value for the quality, in person the color is a shade darker and a bit more blue than purple under most lighting.
Lawsonite - ex Vaux, type locality, exceptional
stock #19.1-803
Tiburon Peninsula, Marin County
California, United States
6.8 x 4 x 3.1 CM (cabinet)
price: $2950
Spring 2020

A superb specimen with exceptional provenance. From the famed Vaux collection this specimen from the original find has a 1897 date on the reverse of the label. Lawsonite is a fairly rare mineral and these are huge crystals for the specie. This old find was also the source of the best Lawsonites ever found, and this specimen is superb, one of the very best. Vaux was a very selective collector famed for his taste and care in selecting for his personal collection which was one of the best of his era. These Lawsonite crystals have sharp striated faces, choice luster, excellent blue color and reach 2 CM. I have only ever seen one specimen with larger crystals, it was the piece from the Roebling collection at the Smithsonian, but on this Vaux specimen the crystals are more perfect with better color and form. The matrix is mostly Glaucophane, in micaceous form, the whole specimen displays very well. Original handwritten Vaux label included which also notes this piece is 64.6 grams. An important piece, this is a true classic.
Axinite
stock #20.1-113
New Melones Spillway (Dam site), Calaveras County
California, United States
4.3 x 3.2 x 1 CM (miniature)
price: $290
Spring 2020

A small, super clean matrix plate of perfect, gem clear Axinite crystals. A modern classic from the best find ever made in the USA. Close inspection shows very sharp glassy crystals with several habits many of which are free standing prisms. Smokey red-brown color with fine transparency. Ex collection of Brett Keller, a choice miniature.
Andradite- Ex Carter Rich
stock #16.1-126
Nance Pegmatite mine, Moneta Forest, Bedford County
Virginia, United States
3.2 x 3.6 x 2.5 CM (miniature)
price: $290
Spring 2020

A single crystal of Andradite Garnet from this little known Virginia locality. Ex Carter Rich specimen, it is rare to see any good pegmatite specimens from this area of Virginia. The crystal is about 70% complete, there is a contact area on one edge and backside but from the front side most faces are sharp and show good form. Cater had offered this specimen for sale in 2009 for 550.00 he considered it significant.
Spangolite with Brochantite, Barite etc
stock #19.1-450
Blanchard Mine, Bingham, Hansonburg District, Socorro County
New Mexico, United States
8.2 x 6.3 x 2.7 CM (cabinet)
price: $140
Spring 2020

A complex specimen with a mix of bright blue Spangolite crystals in several patches mixed with Brochantites. The Spangolites are sharp and gemmy under good magnification, the matrix is quite colorful and more rich than typical from this great USA locality. Typically Spangolite is a micro mineral in most collections, this has enough good coverage to be visible by naked eye but certainly far more beautiful under magnification.
