Jasper Pseudomorph after Barite rosette -Old find
stock #17.1-889
Fruita, Mesa County
Colorado, United States
2.9 x 2.7 x 2.5 CM (small miniature/ large thumbnail (toenail))
price: $290
Pre Holiday 2017

A rare old Colorado classic Pseudomorph specimen from Mesa County, Colorado. From the Collection of the late Dr. Warren Johannson, he obtained this in trade with Amherst College in the mid 1930s. Old label attached dates this to 1910 vintage, but it may be older still. The red Jasper has fully replaced the individual Barite crystals perfectly in this rosette cluster. In fine condition, complete all around. Almost impossible to find now, choice.
Fluorite on Quartz -Fine Octahedral crystals
stock #17.1-658
Riemvasmaak, Kakamas district
Northern Cape Province, South Africa
6.2 x 3.6 x 3.6 CM (cabinet)
price: $1250
Pre Holiday 2017

Very sharp transparent and bright green Octahedral Fluorites are in an esthetic cluster. The main crystal is very well isolated and absolutely perfect which is quite rare. The matrix is all crystallized milky quartz that makes a good contrast with the Fluorites. Riemvasmaak octahedrons are highly respected and among the worlds best, they have been found sporadically for about 10 years, currently there is no new production. Choice pieces of this quality can be very expensive, however, this is especially reasonable from the last good finds in 2014.
Botallackite
stock #17.1-886
Cligga Mine, Cligga Head, Perranporth, Perranzabuloe, St. Agnes District
Cornwall, England
11.9 x 8.8 x 4.9 CM (cabinet)
price: $250
Pre Holiday 2017

A very large specimen of lustrous Botallackite from Cornwall. In several habits but mostly accicular free standing crystals in several vugs. This could be trimmed to make several specimens if desired, but is fine as is to my eye. A Cornish classic copper specie, a paramorph of Atacamite and Clinoatacamite, this specimen seems to have a druse of Langite (not x-rayed) as well. Botllackites is quite rare and when from other localities are not nearly as attractive as these.
Vanadinite- USA classic locale
stock #17.2-887
Pure Potential/ N. Geronimo Mine, Silver dist., Trigo Mts, La Paz County
Arizona, United States
2.7 x 1.6 x 1.4 CM (thumbnail)
price: $80
Pre Holiday 2017

An intense red thumbnail of gemmy, perfect condition prismatic Vanadinite. From the modern classic locale of the Pure Potential mine, these crystals are lustrous, transparent and have both prisms and hoppered forms.
Fluorite- Elongated gemmy cubes
stock #17.1-888
Cantera Llamas, Duyos, Caravia
Asturias, Spain
3.7 x 2.4 x 2 CM (small miniature/ large thumbnail (toenail))
price: $160
Pre Holiday 2017

A super clear, nearly colorless (with a very slight tinge of purple) cluster of two elongated cubes. The crystals are in epitaxial orientation as well. The Fluorites from Llamas are almost always beveled on the edges and often elongated, sometimes on two different axis as is this one. No matrix at all, the back and underside were contacted and recrystallized, and one old cleavage break has also had some regrowth. The facing side for display is almost air clear, sharp and lustrous. A very good example of this small but impressive locality.
Diopside on Graphite
stock #17.1-885
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
2.9 x 2.2 x 2.3 CM (small miniature/ large thumbnail (toenail))
price: $390
Pre Holiday 2017

The gem Diopside crystals from Merlani are modern classics and can have brilliant form as seen here. The color is a yellow to pale greenish hue and the crystals are complete all around, undamaged and statuesque. The contrast with the Graphite adds a nice balance and the complex modified terminations are very distinctive. Good luster with gem clear areas but more translucent than transparent overall.
Vesuvianite
stock #9.1-W159
Jeffrey Mine, Asbestos
Quebec, Canada
4.1 x 3 x 1.5 CM (miniature)
price: $900
Pre Holiday 2017

A colorful and very well formed Vesuvianite with a main crystal showing an unusual shortened prismatic habit. From the great heyday of the Jeffrey mine, now sadly closed forever, this location produced the worlds very best Vesuvianites in many colors and forms. The main crystal is 2 CM across diagonally and well isolated from the mass of crystals and in fine shape. Rough areas and contacts exist but are mostly on the sides and back of this specimen. Color zoning and glassy luster give this extra pop in person.
Hemimorphite -radiating sheaf habit crystals
stock #17.1-884
Mina Ojuela, Mapimi
Durango, Mexico
5.8 x 4.6 x 3.9 CM (cabinet)
price: $380
Pre Holiday 2017

A radiating ball like spray of blue hued Hemimorphite crystals from the famed Mina Ojuela. The individual sheaves reach 1.3 CM and are somewhat zoned, a hint of green copper secondaries are seen as well. Unlike most of the Hemimorphites from this locale, these are opaque crystals and the luster is subdued overall but have a sparkling secondary coating of smaller clear Hemi crystals. The display area in in fine condition but the back and underside have some damage or contacting. Some minor Goethite is also present as small spheres. Not typical at all, this is an odd yet pretty specimen.
