Chrysoberyl - Twinned crystals
stock #19.1-449
Espirito Santo
Espirito Santo, Brazil
3.1 x 2.4 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $680
Spring 2020

A floater cluster complete all around of Chrysoberyl crystals that range from translucent to transparent. A pale yellow-green color with some frosted faces and others that are bright and lustrous. Some chipping on the underside (not seen when displayed) is the only damage to note, some of that seems to be partly rehealed, so this is a natural break. Otherwise this is in fine condition overall and weighs 19.2 grams.

Hambergite on Smokey Quartz
stock #AX-30-036
Shengus (Shingus) Haramoush Mts. Skardu District
Gilgit-Baltistan, Pakistan
6.3 x 4.5 x 4.2 CM (cabinet)
price: $520
Spring 2020

A cluster of milky white Hamburgite crystals are perched protruding from the side of a smokey Quartz. The Quartz is doubly terminated and makes a contrast with the Hambergite. Individual Hambergite crystals reach 2 CM and they are in a stacked arrangement, showing well a prismatic form not the usual fibrous look. Transparent on thin edges but mostly translucent, this is a nice example of this uncommon Beryllium specie. Ex collection of Thomas Fitzpatrick, vintage late 1970s.

Fornacite on Dioptase (Type Locality)
stock #20-FC-115
Reneville Mine, Reneville Kindanba District
Pool Department, Republic of Congo (Brazzaville)
4 x 3.3 x 2.5 CM (miniature)
price: $1600
Spring 2020

Fantasticly rich, dense clusters of Fornacite crystals on Dioptase crystals. Fornacite is a rather rare mineral but nearly always seen just as micros with very small isolated crystals. This is an amazingly rich specimen with eye visible crystals in groups that are up to 2.5 CM across! The matrix is an attractive mix of Dioptase crystals and balls of Plancheite. The crystals are lath shaped and many are free standing, most are a dark olive green ranging to as brownish yellow with backlight. Under strong magnification a few dark green balls are seen that may be Mottramite but are not identified. From the type locality, this is a superb and important piece for this rarely displayed mineral. None of us have ever seen any piece with so much of the specie and so easily seen.

Titanite var. Sphene
stock #15.1-943-(CN2901)
Capelinha
Minas Gerais, Brazil
4.8 x 4.2 x 2.8 CM (miniature)
price: $440
Spring 2020

A choice cluster of old time Sphene crystals with a small bit of matrix. In person these are quite gemmy, very transparent and have fantastic growth structures on several faces. In fine condition there is one small chip on a crystal edge that is the logical base of the specimen and not visible on display. Ex Commercial Mineral Corp (a NYC based dealer) The label for this dates after 1956 though the vintage is likely mid sixties. Ex Charles M. Noll and Jimmie Dufoe collections as well. Presents well from several angles, best appreciated in person.

Bornite pseudo after Chalcocite
stock #14.1-211
Levant Mine, Trewellard, St Just,
Cornwall, England
5.5 x 4.7 x 2.7 CM (small cabinet/ large miniature)
price: $650
Spring 2020

Very fine classic specimen, ex George Robinson collection with sharp, free standing crystals. This specimen is currently pictured on Mindat it is the first specimen in the St Just Bornite section. The shape of the original Chalcocite shows some cyclic twins that are perfectly preserved. Some of the crystals may still have some Chalcocite inside. The exterior shows the patina of Bornite and is quite attractive. In fine condition as seen a choice old classic piece

Pyromorphite
stock #16.1-254
Level 9, Jersey Vein, Bunker Hill Mine, Kellogg, Coeur dAlene District,
Idaho, United States
5.7 x 4.4 x 3.3 CM (cabinet)
price: $1350
Spring 2020

Well formed "wet look" crystals of green and orange Pyromorphite clustered on a contrasting matrix. From the great finds at Bunker Hill Mine, this is a very fine example with especially bright luster and top form. Individual crystals reach to 1.3 cm and are in fine condition. The orange color crystals are much less common and are sometimes called Arsenian Pyromorphite, although there may not be much or any Arsenic in them. Sharp deep orange crystals are quite rare, most are more botryoidal and do not have sharp faces. This specimen does have some small but clearly sharp prismatic orange crystals. Overall very esthetic.

Stibnite
stock #9.1-247
Cavnic
Maramures, Romania
6.7 x 5.2 x 4.8 CM (cabinet)
price: $380
Spring 2020

An esthetic classic Romanian Stibnite crystal cluster with colorful patina on several crystals. This is a radiating group of metallic crystals that is damage free and looks good on all sides. This is an older specimen (30 years or more) from the Cavnic mines that have been closed for a few years. These older stibnites are unique in their habit and look and are clearly recognizable being unlike those from other localities.

Topaz on Quartz with Muscovite etc
stock #20.1-105
Sakangyi-Kyauk-Pyat-That, Mogok, Pyin-Oo-Lwin,
Mandalay Division, Myanmar (Burma)
4.7 x 4.2 x 2.8 CM (miniature)
price: $260
Spring 2020

Several glass clear, colorless Topaz crystals in perfect condition are sticking out of a Quartz crystal matrix. From the Pegmatite of Sakangyi, which had been the source of the best of the Myanmar Topaz, but is now idle. In fine condition, this is a nice example of the occurrence and looks fine from several angles.
