We have all seen numerous garnets frm this location in recent years, but some are just so outstanding they rise above the crowd,. This piece, illustrated in teh China issue of ROCKS & MINERALS, is one such. It is really breathtaking in the quality of the color contrast; and the lustre and color are just top percentile.

Even rarer than a papagoite inclusion is the related copper species AJOITE. Here we have an UNPOLISHED natural DOUBLY-terminated crystal that displays about the richest zone of concentrated ajoite inclusion you can ask for, and the most ajoite I have ever seen in one spot on one crystal. Truly an exceptional miniature by ANY standard for the collector of all things quartz, copper, south african, etc etc.

This was purchased in 1999 directly from the collection of the deceased dealer Luis Leite, a well known specialist in rarities and in Brazilian classics after whom the species Leiteite was named. It is one of the finest examples of a Brazilian milarite I have come across, in any size, but happens to be a particularly balanced thumbnail specimen. Milarite is a highly coveted, yet rare, hydrated, potassium, calcium, aluminum, beryllium silicate. It is best known from the Alps and Brazil, plus a small 1970s find in Mexico. This specimen features a fine, lustrous and translucent, apple green, milarite crystal, measuring 1.5 cm in length, perched on quartz crystals, reaching 2 cm in length. Aesthetic and important! It is most unusual to get specimens with such a nice crystallized association - usually the milarites were found spaced out much more infrequently for the surface area and on generally ugly matrix (from all the locales). These are about 20 years old, and none of quality have been found since the mid-1980s to my knowledge. I think this is just a superb thumbnail for both the significance of the species, AND the balance and aesthetics of the piece itself. The crystals are also of large size for both the locality and for the species, surpassed only by a few freakish specimens from the Alps perhaps. They have excellent lustre and translucency, and it would be very hard to find a competition-level display quality thumbnail of such quality on the market today. Joe Budd photos
SUPERB, super-rich specimen featuring a very rich inclusion of this rarity! Specimens of this quality came out in the 1980s and are seldom seen today. This piece is complete all around, and undamaged, although the color is concentrated to the front side and display face shown. This would be one of the very best I have seen for sale recently. Amazingly, as it is the fate of most, it has not yet been polished.
On a matrix of sugary-looking, white quartz are aesthetically perched, several,brown, lustrous, scheelite crystals, to 2.5 cm across. All the sparkly, sugar-like material from the halfway point of the piece down is a thin druse of colorless, beautiful, sparkling FLUORITE overlaying the qartz matrix and part of the scheelite pocket! The scheelites are supremely good for the locality and have a rich wet lustre to them! This is a spectacular specimen for the locality for both the size overall and the perch on quartz as you see it. Most unusual also, because of the fluorite association. A few scheelite crystals are even doubly terminated. Normally the Colorado scheelites do not do a lot for me, but this is special! Comes with base.

A well formed, lustrous, golden-brown crystal of sphalerite, 3.5 cm across, sits majestically on white quartz and sharply crystallized, brassy, chalcopyrite crystals, to 2 cm across. BETTER IN PERSON, this is a combination of flashy metallic hues with some white contrsat at the edges! It is a spectacular display specimen and for quality from this old locality, is something rare on the market today. I do not know how old it is, only tha tI am told these are generally pre-1950 and certainly I do not see pieces of this magnitude pop up often. This is certainly one of the best combo specimens I have seen from Japan. It was long in Gene Meieran's sulphide collection before I traded it out of him.
A crust of botryoidal, translucent, lustrous, opalescent green, "gem silica" / chalcedony has formed over bright green chrysocolla. The spheres reach 1.3 cm across. This exquisite specimen comes with an old, pre-1940 label from preeminent dealer, Lazard Cahn.
A crystal druse of lustrous, emerald green, pseudomalachite has formed on colorless, quartz crystals, to 2.5 cm in length. This is an oldtime specimen from the heart of Cornwall. Most unusual - I have not seen another
Sharp rosette of gorgeous crystals from this old and desirable US locality for rose quartz! rare!
ex. Dr. Frederick Pough
This is the best Newry mine rose quartz I have seen for sale. it is really very colorful for the locale and big, too. Interestingly, it has minor, tiny crystals of eosphorite on it!Very Rare, very pretty oldtimer!
Gorgeous rolling plate somewhat translucent and very sparkly, on quartz karst matrix.
A beautiful, curving specimen of nearly solid amethyst, translucent.
One of the best in the lot for its undamaged, 3-dimensional, rolling surface and intense coloration! It has great form, and is complete on the front as shown, contacted just on the sides.
Beautiful plate, fairly flat but with a slight roll to the surface, on karst quartz matrix
