Rutilated Quartz and Hematite
stock #13.1-175
Novo Horizonte
Bahia, Brazil
3.8 x 2.4 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $190


A cute toenail sized rutilated Quartz that sits on bladed Hematite crystals that are also Rutilated. The Rutile hairs are bright golden color and very sharp, clearly seen both inside and out of the Quartz. Rutile on Hematite and Rutile inside Quartz are both often available, but it is quite uncommon to see both together like this.
Elbaite -multi color zoned
stock #17.1-412
Santa Rosa
Minas Gerais, Brazil
3 x 1.5 x 1.4 CM (small miniature/ large thumbnail (toenail))
price: $420


A glassy, clean and many colored crystal of Elbaite from an old find (1970 vintage) at Santa Rosa. I count four or five colors at least with some gentle gradations. The termination is the flat basal type and has a hint of blue in some lighting but not so strong as a classic blue cap. In excellent condition though there are some tiny rough spots that are sub millimeter in size and not easy to see . A very nice gem crystal with a choice color pallet zoning from this get locale.
Spinel on Quartz and Calcite
stock #18.1-995
Pein Pyit, Mogok, Sagaing District
Mandalay Division, Myanmar (Burma)
2.8 x 2.3 x 1.3 CM (small miniature/ large thumbnail (toenail))
price: $350


Well exposed, complete octahedron of ruby Spinel perched on a sliver of matrix. A few tiny flecks pf Pyrite are present as well, but mostly this is about the deep red Spinel crystal. This has some of the typical pitting, rounded edges and adhering matrix but is otherwise a very pretty dark red gem crystal, There are a few small gemmy Spinel seen with magnification on the flat sides of the matrix, they are almost invisible by naked eye. Myanmar has a well deserved reputation for exceptional gem crystals, especially for Rubies. However for hundreds of years Spinel were often substituted for Ruby. The gem fields in Mogok produce far more Spinel than Ruby, and it has been increasing in acceptance as a legitimate and valued gem. This is a nice affordable crystal that is above average in quality.
SOLD Fluorite pink, new find
stock #SOLD 19.1-674
Huanggang Mine, Chifeng Prefecture, Hexigten Banner, Ulanhead League
Inner Mongolia Region, China
3.5 x 2.9 x 2.5 (small miniature/ large thumbnail (toenail))
price: $0


A killer small miniature from the great new finds at Huangang, A perfect cluster of two sharp deep pink to almost red Fluorites. These Octahedrons are included by fibers of an Asbestos like mineral, perhaps Byssolite. The condition of this is perfect on all sides, each corner and edge is undamaged. This was a very large and impressive find but this level of perfection was very rare. This was selected from hundreds of pieces. This style of Fluorite is quite unique and absolutely unlike any pinks from any other locality. The faces are lightly frosted and the interiors are very clear. The included fibers are easily seen. The large number of specimens recovered has helped keep the prices reasonable for such incredible specimens.
Cubanite
stock #13.1-240
Henderson Mine, Chibougamou
Quebec, Canada
3 x 2.3 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $625


An esthetic cluster of shining Cubanite crystals all showing classic twinningset on just a sliver of matrix. The Henderson Mine at Chibougamou has been closed for many years, it was the only source of these fine, sizable Cubanite crystals. The largest crystal in this cluster is is 2 CM across, and sits well on top of the specimen. Close exam shows some minor bruising, contacts and natural cracks, so this is not for perfectionists, but as Cubanite is a very delicate mineral this is in relatively fine condition. and far better than average. Some areas that look like damage in the photos are on inspection fully intact and crystalized with a rough texture. The metallic luster is excellent and has a nice patina. These are a modern classic and somthing of a "holy grail" for most collectors, the starburst twinning habit is especially desirable. An excellent value for the quality.
Tanzanite (blue Zoisite) gem crystal
stock #19.1-869
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
3 x 1.1 x .6 CM (small miniature/ large thumbnail (toenail))
price: $750


An especially vibrant, sharp and clean gem crystal in impeccable condition. The intense blue hue on this is far better than the average and the crystal shows well the famed color shift to a strong royal purple as it is rotated. As the gem values for good Tanzanite is so high the cost of a good specimen with top color can be prohibitive. This is an exception, a small miniature with big visual impact for well under 4 figures. Many Tanzanites have been heat treated to enhance color, it is almost impossible to tell. This one has a hint of red color when viewed down the C axis from the termination. That is said to be a good indication that the color is fully natural.
SOLD Bournonite - Cogswheel type crystals
stock #SOLD 19.1-856
Colavi Mine, Machacamarca district, Cornello Saavedra Province
Potosi, Bolivia
3.1 x 2.6 x 2.4 CM (small miniature/ large thumbnail (toenail))
price: $0


A fine complete cogswheel cluster of Bournonite crystals that is perfect on all sides, undamaged and with classic gunmetal luster. Bournonite is a delicate mineral and perfect clusters of this sort are quite rare. A tiny bit of adhering matrix gives some nice contrast. This is a very fine and unusually sharp specimen from Bolivia that really looks just like a vintage Herodsfoot specimen. From recent mining this is obviously far less expensive than the English classics!
Amethyst -scepter with Rutile inclusions
stock #19.1-855
Karur
Tamil Nadu,
3 x 2 x 1.3 CM (small miniature/ large thumbnail (toenail))
price: $340


A delicate slender scepter of well formed Amethyst rises from a cluster of smaller crystals. Very fine esthetics and good color in perfect condition. The scepter is included by red needles of Rutile best seen in the clear parts of the head. This specimen also has the rare hexagonal hole or negative crystal in the top of the termination, this is especially impressive with magnification. Despite the small size this has a strong visual impact and is especially choice on close examination.
