Fornacite on Dioptase (Type Locality)
stock #20-FC-115
Reneville Mine, Reneville Kindanba District
Pool Department, 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-CN-2901
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.
Epidote and Quartz - Classic USA
stock #10.1-336
Green Monster Mountain, Prince of Wales Island, Prince of Wales Island
Alaska, United States
4.4 x 3.8 x 3.5 CM (miniature)
price: $250
Spring 2020

Epidote from the famed Green Monster Mountainon Prince of Wales Island is a classic and desirable in any collection. The best Epidote are sharp, lustrous and dark oily green often with contrasting Quartz. This miniature has that classic look and displays very well. There is damage to note on several Quartz crystals some of which shows rehealing. This keeps the price far lower than usually seen of Epidote of this quality. The main free standing Epidote are in fine condition and are the focal point of the piece. The bright luster on this small piece is especially eyecatching. Vintage about 1960, a very good value.
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 gret finds at Bunker Hill Mine, this is a very fine example with especially bright luster and top form. Individual crystal reach to 1.3CM 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 (Kapnic)
Maramures, Romania
6.7 x 5.2 x 4.8 CM (cabinet)
price: $380
Spring 2020

An esthetic classic Roumanian 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 speciment (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.
Cassiterite- gemmy crystals on matrix
stock #10.1-320
Ximeng County, Pu'er Prefecture
Yunnan, China
5.8 x 3.7 x 3.3 CM (cabinet)
price: $390
Spring 2020

An nice older Chinese specimen of the dark transparent Cassiterites from Ximeng that are now very uncommon. These lustrous crystals on contrasting matrix show both twinned and untwinned forms. These are a dark brown to almost golden on some edges and are prettier in person. This find was unlike any other Cassiterites found in China, being more similar to the best from Bolivia, yet still recognizably different.
