OKF-061 Wulfentite Silver Bill Mine, Gleeson, Arizona. Ex. Dr. Steven Chamberlain collection. This pieces is a very fine grouping of butterscotch yellow wulfenite crystals to 2.1 cm each. They are on a tiny piece of matrix and stand up perpendicular to it in a pleasing arrangement. Fine views from all sides on this specimen. One crystal appears damaged but it is simply an odd shape. One smaller crystal has an edge cleaved which is visible with magnification. Overall condition is exceptional. Glued into Perky box. 3.6 x 3.4 x 2.2 cm overall. The specimen fills the box to capacity. 130$

OKF-062 Babingtonite and Quartz Hampden Quarry, Westfield, Hampden Co., MA. Ex. Dr. Steven Chamberlain collection. Prev. Ward’s Minerals. Beautiful babingtonite crystals sit on clear to milky quartz crystals in this fine specimen. The babingtonites are an east coast classic and up to 1.6 cm in length in parallel growth. The primary crystals sit up high on the quartz crystal matrix and display well. The babingtonite is of the highest luster, nicely formed and aesthetic. Some of the quartz is damaged but this does not distract from the quality of the important mineral here. The entire specimen measures 3.4 x 2.5 x 2 cm. 140$

OKF-066 Malachite pseudomorph after Azurite Morenci Mine, Greenlee Co., Arizona. Ex. Dr. Steven Chamberlain collection. For the Morenci Mine this is a very unusual piee. The entire specimen is a single azurite crystal measuring 2.4 x 2.4 x 1.7 cm which has been replaced by malachite.

OKF-069 Azurite, Malachite and Quartz New Cornelia Pit, Ajo, Pima Co., Arizona. Ex. Dr. Steven Chamberlain collection. Here is a both old and beautiful specimen of a desirable mineral. Several large double terminated crystals make up the bulk of the piece which measures 3 x 2.8 x 1.4 cm. The big crystals are 2.1 to 2.4 cm each. They run in roughly parallel directions and are attached to a small piece of matrix. They are of the highest luster and complex in their crystallography. A tiny cluster of quartz crystals are attached to the base of one of the azurites. The malachite alteration on several of the azurite’s surfaces adds nice contrast in colors. Its luster is lower and the surfaces created by the pseudomorph is not as smooth as the original azurite. This is an exceptional TN specimen from an unusual location. 500$

OKF-080 Hematite pseudo. after Magnetite Digby, Nova Scotia, Canada. Ex. Dr. Steven Chamberlain collection. This specimen is a real stunning example of replacement. The stack of magnetite octahedrons is now hematite, which is not obvious from external appearances. The luster remains highly metallic and the form immaculate. When turned over and viewed from the underside the picture is completed. The hollowed out structure of the lower magnetites clearly showed the anticipated replacement (which may in fact now be goethite). 3 x 2.5 x 2.5 cm. A damage free, rare and interesting specimen which shows well from any direction. 100$

OKF-082 Copper pseudo. After Azurite Georgetown District, Grant Co., NM. Ex. Dr. Steven Chamberlain collection.

This one measures 3.1 x 2.8 x 2.5 cm and ahs crystals to approx. 1.5 cm wide. These are not veryy common anymore so damage free, well formed pieces like this one are becoming difficult to find except in old collections. 100$
