Adamite with Calcite
stock #17.1-617
Mina Ojuela, Mapimi
Durango, Mexico
4.9 x 3.8 x 3.8 CM (miniature)
price: $125
Worldwide mix summer

Bright lemon yellow crystals that are sharp and gemmy contrast with white Calcites. Choice and lustrous, this is an older specimen from the "golden era" at Mina Ojuela. Vivid Fluorescence and in great condition.
Benstonite on Fluorite
stock #15.1-967-SM-3121
Cave-in-Rock, Hardin County
Illinois, United States
6.7 x 5.7 x 4.6 CM (cabinet)
price: $450
Worldwide mix summer

Benstonite in unusual distinct crystals clustered on Fluorite cubes. Ex Charles Noll collection, a choice example of this uncommon mineral that has always been a very desirable rarity from this region. The Fluorite cubes are also very sharp and clean with strong Fluorescence. These are only available from older collections and most are just a whitish coating on other minerals. This almost certainly came from the Minerva mine but the label does not give that specific detail so we leave this listed as Cave-in Rock only.
Malachite - Primary crystals, classic locale
stock #15.1-1064-SM2923
Andrassy II. Mine, Rudabanya, Rudabanyai Mts.
Borosod-Abauj-Zemplen Co., Hungary
7.6 x 5.2 x 3.2 CM (cabinet)
price: $750
Worldwide mix summer

An old, well formed and crystallized Malachite from Rudebanya ex Charles Noll collection. The Malachite is quite lustrous and contrasts with the gossan matrix, but this is nearly all Malachite. This is also a well formed and fine Primary Malachite, not a pseudomorph. The luster is bright and satin like with clustered groups of prismatic crystals in spherical arrangements. In excellent condition, we do not know the vintage of this piece but the style is only seen in very old collections, and the locality has been mined since the copper age, it is one of the oldest mineral sites in Europe. Impossible to find specimens of this caliber today.
Gold - exceptional crystals, multiple forms
stock #18.1-AX-12-281
Alta Floresta Gold Province, Alto Floresta
Mato Grosso, Brazil
2.3 x 1.3 x 1.1 CM (thumbnail)
price: $1750
Worldwide mix summer

A natural sculpture in Gold, this is a remarkable cluster of several different forms and habits. Any angle of view has considerable impact and interest with these forms. From old finds at Matto Grosso (more than 20 years ago) this is an especially dramatic piece with skeletal and hoppered forms based on elongated octahedrons. 9.1 grams and all of it very well crystallized, a strong display thumbnail of fine competition grade.
Grosular (chrome) on Chrome Diopside
stock #18.1-269
Orford Nickel Mine, Brompton Lake, Sherbrooke
Quebec, Canada
5 x 2.8 x 1.8 CM (miniature)
price: $90
Worldwide mix summer

Intense green small Grossular are scattered on greenish to grey color Diopside. From the Orford Nickel mine, these were called Uvarovite for many years, and this has an old label with that name but this is absolutely all grossular. These are still occasionally found at this venerable locale, but this piece has especially bright green color and larger than typical garnets. Choice for the locale, and an esthetic combo. Collected by Les Hitchings in 1967.
Mimetite -classic, modified hexagons
stock #16.1-466-CN2141
Mount Bonnie Mine, Grove Hill
Northern Territory, Australia
4.1 x 4 x 2.2 CM (miniature)
price: $650
Worldwide mix summer

A fine Mimetite cluster on a gossan matrix, from the classic old finds at Mt Bonnie. These are still considered some of the worlds great Mimetites, and this piece shows the most desired flattened hexagons with modified edges. Fine luster, undamaged condition and with a bit of zoning. This could be trimmed to a thumbnail of competition grade but we like it as is. Ex Charles Noll, Nick Carruth, David Crawford and others (unattributed labels). No other localities since this find has produced this style of Mimetite, it is quite distinctive.
Fluorite -etched edges and faces
stock #18.1-249A
Elmwood Mine, Carthage
Tennessee, United States
2.4 x 1.8 x 1.4 (thumbnail)
price: $220
Worldwide mix summer

A tasteful thumbnail of zoned Fluorite showing very fine stepped and etched faces. From the Elmwood mine ex Larry White collection, this is a strong display piece with minimal matrix. In fine condition, there is a cleave on the backside (not seen) and a micro chip seen with magnification, otherwise pristine and now that the mine is closed there will be no more. It has been remarkable to many that this incredibly productive locale had so few good thumbnail sized specimens, everything was usually far larger and in most pockets nothing small was collected.
Barite on Fluorite
stock #18-AX-13-013
Minerva Mine #1, Rosiclare Level, Cave in Rock
Illinois, United States
10.4 x 6.5 x 3.3 CM (cabinet)
price: $130
Worldwide mix summer

Sharp contrast of the bluish white Barite crystals with the purple Fluorites in a classic combination. Ex York collection. This is dated 1992, so it is from the last part of the mining period. In fine condition the Barites are all perfect, undamaged, there are some very tiny cleaves on Fluorites that is not noticeable. A modern US classic that is better in person.
