OKH-681 Hematite pseudomorph after Magnetite Payun Volcano, Altiplano de Payun, Matru, Mendoza, Argentina. Ex. Dr. Steve Chamberlain Collection, circ. 1996. An amazingly aesthetic example of this fine material. Highest luster possible. Zero damage. Fantastic form with three fully terminated spires rising from a small fully terminated base. The piece is a complete floater. A wonderful example of parallel growth. Must be seen to be appreciated. Comes with a custom engraved acrylic base. 7.9 high, 3.7 wide and 1.7 cm thick. Fantastic piece. Likely the finest small cabinet specimen of this material of which I am aware. $995

OKI-630 Acanthite pseudomorphs after Argentite Mina del las Rayas, Guanajuato, Mexico. Ex. Dr. Steve Chamberlain Collection. This is a special piece for the TN collector who seems to have everything else. It is the finest of these which I have seen as far as aesthetics go. Larger crystals can be found and certainly larger prices (mid four figures) but this one has the looks, sharp crystal form and luster which most collectors desire more than crystal size alone. It measures 2.5 x 1.5 x 1 cm and is somewhat three dimensional. It branches out in a sweeping display with the larger crystals (to .8 cm each) on its upper sections. There is no damage to this floater. There was once contact with what may have been calcite crystals on its backside. The contact has a thin layer of what appears to be pyrite now forming casts which would have extended over the missing mineral’s crystals. A truly fine example, and competition grade TN, of material which is usually nearly globular in shape and far lower in luster. 1,500$

OKC-069 Dioptase on Calcite Argentina. Ex. Dr. Steve Chamberlain Collection. Unusual location for this species. Gemmy green crystals to .7 cm on small aggregates. Looks very different from African and Russian material in that the crystals are acicular in form. 60$
These tourmalines and magnesites from South America are special. All the pieces to follow are from the famous collector and dealer Carlos Barbosa. The specific local is Brumado, Bahia. The uvites are red, green and sometimes a light gray in color. They are gemmy and attractively perched on rhombohedral magnesites. These magnesites are clear to milky white and sometimes have brown phantoms. They will have a very basic description by the photo and a 1 cm tag will be by the specimen for scale. There is rarely any damage to these specimens and both sides of the piece are often mineralized. The form, luster and aesthetics on all the specimens are superb. They are priced at what is approximately 1/3 to 1/2 of what a conservative retail price should be. I hope you enjoy there beauties.
