OKF-192 Natrolite and Rhodochrosite De-Mix Quarry, Mt. St-Hilaire, Québec Canada. Ex Dr. Steve Chamberlain collection. This specimen is an impressive miniature which measures 4.1 x 3.5 x 2.8 cm. There are several other species besides the primary minerals but what makes this piece great is all the double terminated natrolite crystals. They are up to 3 cm each with beautifully formed in luster is terminations. The prism faces have more of a silky luster. The rhodochrosites range from micro to .7 cm each. There is a large crystal contact on one of the natrolite crystals in some minor Styrofoam on the back of the specimen. An excellent example of this species for this location. $200

OKF-203 Rhodochrosite on Marcasite Oppu Mine, Aomoriken, Honshu Prov., Japan. Ex Nancy Collins collection. Specimens don't get much more desirable than this one. The piece measures 9.4 x 6.5 x 4.7 cm and is almost entirely solid pyrite. On the pyrite are mounds of low luster pink rhodochrosite. Much of the lower sections of the specimen, its base, are also mineralized. One small chip a pirate is missing it is certainly not distracting to any of its views. This piece sits in displays wonderfully. An important piece from a desirable location. Price on request.

OKF-220 Hemimorphite from a small unnamed prospect, Malipo, Wenshan, Yunnan Prov., China. Ex Michael Walter collection. This large plate of hemimorphite is well mineralized on both sides. There is some minor staining and very minor scuff marks but overall this is a superior specimen which had been in my Chinese suite for many years.

OKF-221 Rhodochrosite Casts Stratoni, Greece. Ex Nancy Collins collection. The rhodochrosite crystals which make up this specimen are intergrown and in epitactic overgrowth on an unknown species of crystal. I would assume these were originally dolomite, perhaps siderite crystals of very large size. Maybe they were even rhodochrosites and the rhodochrosite remaining is a second generation. Whatever the case it is made for a very displayable cabinet size specimen of an uncommon mineral from a rare location in an unusual form. There is minor pyrite and tiny double terminated quartz crystals mixed within the specimen’s matrix. This is simply an outstanding specimen, perhaps the best one I've ever owned from any location. It has so many things going for it that it is almost difficult to describe. The cast reach 4.3 cm on edge and are up to 3 cm deep. They stand up well off the matrix which is also fully crystallized on its backside, but does not have the large rhodo casts seen on the front. There is no damage whatsoever to the stellar piece which displays beautifully the specimen is far better in person and not as fragile as it looks. I do not have the astronomical price which one might expect to be associated with piece of this magnitude. He would absolutely be a five figure specimen with another dealer. I would prefer to have it in the collection of someone who takes their rhodochrosite specimens seriously. This somewhat rectangular shape piece measures 10.6 x 8.1 x 6 cm overall. Give me a call and we will talk about how to get the specimen to your collection. Price on request

OKF-222 Analcime, Aegirine, Natrolite, Serandite, Rhodochrosite, Byssolite Mt. St-Hilaire, Québec Canada. Where else besides Mt St-Hilaire can one come up with a combination of species in one specimen such as this! This huge museum grade specimen measures 15 x 12.5 x 8 cm. The largest crystals are 6 cm in diameter. The piece stands on edge beautifully for display at is probably a shocker to anyone who thinks of Mt St.-Hilaire has been a location for micros only. I won't go into detail on all the crystal species measurement’s but let's suffice to say that all are easy to find and well formed. The piece has a medium level luster and I find no damage. This is a museum grade specimen at a manageable collector's price. $595

OKF-223 Kunzite Mawi, Laghman Province, Afghanistan. Here is a beautifully formed etched kunzite a significant size it measures 14.5 cm in length is 4.7 cm wide and 3 cm in thickness. There is an enormous amount of gem rough contained within this piece. Don't get me wrong, I do not suggest it should be converted into gemstones, but its value has to be a least equal to what would be produced if it was. I am price that way below that. The color is very deep and view down the c axis of the crystal and does not look washed out like many kunzites do. It is damage free and extremely displayable. The photographs of this specimen are much lighter that the specimen actually is. Priced way below the standard market value at $680.

OKF-224 Kunzite Kala, Darrah Province, Afghanistan. Here is a beautifully formed tabular 14.7 cm high 4.2 cm wide and .7 cm thick. The color is very deep and view down the c axis of the crystal and a purist slightly light in color due to its being only .7 cm thick. In reality this specimen is of excellent color, displays a wonderful primary termination and is totally re-crystallize where there was once a basal contact. It is damage free and extremely displayable. The piece is deeply striated and a pleasure to handle and inspect. The photographs of this specimen are much lighter that the specimen actually is A fabulous display specimen. $860.

This wonderful large cabinet piece is coated by white barites with a liberal encrustation of gem clear fluorites, approximately 75% coverage, up 1 cm on edge each.

The specimen measures 12.5 cm x 11 cm x 7.5 cm and is also crystallized on approximately 40% of its back. This is one of those rare pieces from a site which never produced many specimens in the first place and is noted for rarely producing any that are damage free. A superb fluorite. $1000
