A fine Fire Agate should look a lot like a fire Opal, this piece does, it is an impressive example. This has very bright fire colors with red, green, blue purple and yellow flashing colors, far better in person. These colors come from inclusions of iridescent Hematite in the clear parts of the Chalcedony. A top grade Fire Agate that has a polished facing surface and is sawn on the back, 17 grams. Fire agate of average grade is currently plentiful but this quality is not, and is often nearly as expensive as Opal.
A very rare and highly sought after Alpine treasure, this is a choice free standing Bazzite crystal on a matrix of Quartz with a few Hematite crystals. Bazzite is the Scandium analogue of Beryl and is classed in that family, most crystals are well under 3mm and are not so easily seen by naked eye. This is a 6 mm crystal with tapered form, some gemmy areas, good blue color and a curve clearly seen without magnification. From a single small but important find in a single tiny pocket in Savoie, France a few years ago. A superb, displayable thumbnail (actually just a hair larger more a toenail size) of a specie almost never available in any size. This is the only the second Bazzite we have ever had for sale and the first that can be seen without a microscope.
Hydroxylpyromorphite on Cerussite
MFouati Mine, Bouenza Department
5.9 x 3.1 x 1.7 CM (cabinet)
A very fine and unusually esthetic specimen of this new and rare mineral. This is a newly recognized specie (2017) and is the Pyromorphite analogue of Hydroxylapatite (Pyromorphite is of course part of the Apatite family). The well formed Cerussite crystal is a super matrix for the white to greenish crusts of micro crystals and masses. This specimen from the Congo is by far the best looking example I have seen. It is uncommon for new or rare minerals to visible to the naked eye and less often colorful or attractive. It remains to be seen if more will be found at MFouati, it is the first find of the specie in Africa. This mineral was previously noted at three localities in Europe and two in the USA as an "unknown, undescribed" specie. In those localities this has been found only in submillimeter crystals and crusts. A superb example with a rich coverage, a superb addition for a Pyromorphite suite.
Andradite (var. polyadelphite)
Franklin/ Sterling Hill
4.8 x 4.1 x 3.8 CM (miniature)
Sharp Franklin New Jersey Garnets with the Orange-Brown color that was once called Polyadelphite. This is a Mg rich type of Andradite, but it is not recognized as a separate specie and the name is not used as much now. This is an old specimen, there are several collection numbers and one handwritten label attached. The main Garnet is 2.3 cm across, the form is quite good and relatively complete for one of these. Classic Franklin material this looks like others I have seen from the Buckwheat but there is no further information. A choice Franklin crystal.
SOLD Azurite -Jackstraw crystals
stock #SOLD AX-19-069
Kerrouchene, Kenifra Province
6.3 x 4.6 x 2.2 CM (cabinet)
Slender Azurite crystals in a jumbled mass with electric bright color. With many fine Azurites available now from several world localities, most collectors have a few at least. However this delicate slender habit from Kerrouchene is quite different and has a unique esthetic. These do stand out. All of these crystals are translucent at the ends, with backlight they really glow. This is not photographed with backlight to give a good sense of the look in a typical display, however with some modern lighting the effect is far more impressive. In very good condition overall, there is some contacting mostly on the back and a few small imperfections.
Scheelite with Quartz and Magnetite
Huanggang Mine, Chifeng Prefecture, Hexigten Banner, Ulanhead League
Inner Mongolia Region,
4.8 x 4.3 x 3.6 CM (miniature)
A fine looking, well formed Scheelite crystal in pyramidal form with a flowerlike Quartz cluster on one edge. Very esthetic, the Scheelite has a glassy, translucent, micro pitted and slightly etched surface that makes a nice contrast. In excellent condition, the matrix at the base of the piece is a mass of Magnetite crystals. The Scheelite and Quartz are in excellent undamaged condition. The Scheelite has a few green coatings and inclusions of Hedenbergite which gives it this color. Far better than the typical Scheelites from here and better in person.
Several well formed textbook sharp Kesterites are well displayed on the contrasting Muscovite (which is also well crystallized). For a few years the Mt Xuebaoding area produced the worlds best Kesterites usually coated with green Mushingtonite. The mining sites have closed and shifted and there is no more. The only source now for a good piece is from an old collection. This piece has sharp crystals up to 1.4 CM though most are smaller. Scattered sprays and balls of Malachite are also present, this was a less common accessory mineral at this find. In fine shape this could be trimmed to several thumbnails or miniatures but is also choice just as it is. A good value for a modern classic now getting quite rare.
SOLD Covellite- Classic USA
stock #SOLD 16.1-531
Summitville District, Rio Grande County
5.8 x 4.2 x 2 CM (cabinet)
Bladed crystals of Covelite are clustered on edge in the classic form from Summitville, Colorad. On this piece the iridescent patina is similar to good specimens from Butte, but has the Colorado form. Crystals are distinct, well separated and sharp, this is nearly pure Covellite just a few tiny bits of adhering matrix. Covellite is a somewhat common mineral but almost always massive. Crystallized Covellite is quite rare as there were only three locations that ever were good sources, at those sites it was still rare. Now all those mines are long gone.
