OKE-413 Inestite N’Chwaning Mine, South Africa. Ex. Jim Turek Collection. This is a special specimen which is of an exceedingly rare mineral in its best form and impressive size. The matrix specimen measures 10 x 6.5 x 4 cm overall and is composed of huge balls of asicular sprays of brownish pink inestite. Tiny clear calcites are on the tips of some of the inestites (almost looking like damage). This specimen is very clean, no damage except along edges from expected contacts, and highly desirable. Great piece! 650$

OKD-115 Goethite Pseudomorph after Pyrite Ross Hill, Transvaal, South Africa. Ex. Dr. Steve Chamberlain Collection. Here is an unusual location for such nice specimens. This material was acquired from Ward’s Science in Rochester back in the 1970’s. I’ve never seen any of these in collections or on the market, so they must have been very short lived. Interesting intergrowth of bars and morphed pyritohedrons in this elongated piece. Nice luster and viewable from all directions. 6.5 x 3.5 x 3.5 cm overall. 120$
