11.6 x 7.4 x 3.4 cm. An elegant quartz "cross" from Panasqueira, with one slender 7-cm crystal growing across a larger crystal that has partly grown around it. There is a minor association of arsenopyrite here.
3.9 x 3.9 x 2.4 cm. From the amazing rhodo find in China last year - a gorgeous combo specimen, where you have not only the platy, deep salmon colored crystals of rhodo, but a row of gemmy quartz crystals that they have grown aesthetically around. There were very few like this! The tips of the quartz crystals could not be preserved in getting this specimen out, but it is still exquisite.
6.4 x 4.4 x 4.1 cm. A RARE and showy specimen of a vug richly lined with lustrous, deep blue, dipyramidal quartz crystals colored by aerinite inclusions from near Malaga, Spain. Aerinite is a RARE silicate, found worldwide almost exclusively in Spain. A well-written article on this find is found in the Mineralogical Record, Volume 27, Number 2, 1996. This is quite good for the material.
5.2 x 5.0 x 3.4 cm. A CLASSIC, OLD-TIME and showy English specimen of discrete and clustered campylite crystals on superbly contrasting oxide-coated quartz matrix. Campylite is the old English name for barrel-shaped mimetite crystals. The gemmy to opaque, yellow-orange crystals reach 1.2 cm. Campylites of this quality are from the famous Dry Gill Mine at Caldbeck Fells and probably date from the 1840s to 1870s. This historic old-timer comes from an old European collection, where everything dates to the 1800s. This whole collection had myriad old materials, though I cannot name the owner, and was well known in Europe. Accompanied by an old faded German label.
9.6 x 9.2 x 5.0 cm. The Braen's Quarry in New Jersey has been a seldom collection quarry for year, but has been a source of excellent Zeolite specimens and associated species. This piece features no Zeolites, but it hosts lovely golden Calcite scalenohedra which are wedged in the middle of a superb quality cast of Quartz after Anhydrite. The cast is especially nice because of the Anhydrite grew in several different directions, creating a wonderful three-dimensional effect. You can see the delicate, thin, bladed, cavities where the Anhdyrite once existed and dissolved away after the Quartz formed around them. A wonderful example of this fantastic phenomenon in the mineral world. Ex. Richard Kosnar Collection.
4.6 x 3.9 x 2.8 cm. This specimen is a great miniature size piece consisting of super quality, sharp, gemmy, lustrous, prismatic, purple color prisms of Amethyst measuring up to 1.6 cm (one of which is doubly-terminated) sitting atop white/colorless, modified scalenohedra of Calcite on forest-green "Chlorite" on matrix. This piece is unusual for Bolivia as it is from an "Alpine-type" locality (non-ore body). This is one of the best pieces from the find for quality, aesthetics and overall appeal. Ex. Brian Kosnar.
7.3 x 5.6 x 5.1 cm. This specimen features green tipped, amazonite crystals, to 5.0 cm in length, in parallel growth along with a translucent crystal of smoky quartz to 2.0 cm in length. It is from the collection of James E. Moresby White. It has never been cleaned since the day it was found and retains pocket clay coating. Ex. Carnegie Museum Collection.
9.6 x 6.5 x 4.8 cm. Nestled in a vug with many colorless quartz crystals are a few, gemmy, light purple crystals, of fluorapatite to 4mm across. A reference piece for the locality, if not a stunning display specimen per se. From the collection of James E. Moresby White. Ex. Carnegie Museum Collection.
4.6 x 3.8 x 2.4 cm. A yellow-orange wulfenite crystal, 1.0 cm across, has been replaced by quartz which has left the matrix covered in a bluish-gray chalcedony. SUPERB miniature with a relatively large crystal form this famous, small, and totally unique Arizona find. Ex. Carnegie Museum Collection.
3.2 x 1.9 x 1.1 cm. A cute and perfect toenail of a beautiful purple and gemmy amethyst crystal jauntily perched on a bit of quartz matrix from the Goboboseb Mountains of Namibia. Each crystal face has a different look and the internal swirl pattern is fascinating. Ex. Dave Mansfield Collection, son-in-law of famed Namibian dealer Sid Pieters.
4.6 x 1.2 x 1.0 cm. A UNIQUE and UNUSUAL quartz find now gone and done with, with specimens hard to get today after 2 years out on the market! A pristine, complete all-around, lightly frosted, water-clear quartz crystal is included with crudely crystallized dark blue/purple fluorite. This showy piece is from a most unlikely locality for fluorite - Madagascar!
3.0 x 2.6 x 2.0 cm. A SUPERB and AESTHETIC specimen from the famous Taewha Mine of South Korea. A 2.4 cm, very gemmy and lustrous, chocolate-brown scheelite crystal is beautifully attached to the side of a water-clear quartz crystal, which is preferentially coated with tan oxides. The scheelite exhibits textbook octahedral form. These scheelites were long considered the world’s finest, until recently surpassed by the new Chinese finds. The back of the scheelite is contacted, but is out of sight. A highly desirable scheelite from this famous locality. Excellent white fluorescence. Ex. George Elling Collection.
6.5 x 4.8 x 2.4 cm. A stunning, VERY AESTHETIC, OLD-TIME specimen of a 3.1 cm, pristine, smoky quartz crystal centrally located on a adularia/quartz plate COVERED with gemmy, pistachio-green epidote crystals. The quality of both species is very high. The prism faces of the smoky are water-clear and the termination faces are distinctively chloritized. It is nearly doubly terminated! This SUPER old-timer comes from an old European collection, where everything dates to the 1800s. This whole collection had myriad old materials, though I cannot name the owner, and was well known in Europe.
18.1 x 12.1 x 7.9 cm. Two large, tabular, 5-cm crystals of smoky quartz lie flat against the matrix of sharp, euhedral crystals of cream-colored microcline - with another quartz of the traditional prismatic form growing at their base. Pale greenish-gray albites are here and there. From a small private collection of long-collected Argentine minerals built up by a US expatriate down there. From the Rumi Tueu Mine.
10.9 x 8.9 x 3.4 cm. Uncommon on the market, a specimen of yellow fluorite from Argentina. The crystals are to 1.2 cm, a pretty golden-yellow color with faint internal phantoms with thin purple outlines. The fluorites sit on a field of sparkly chalcedony. From a small private collection of long-collected Argentine minerals built up by a US expatriate down there.
