RM1402   Hübnerite with quartz

Adams Mine, Cement Creek, Eureka, San Juan Co., Colorado, United States

An excellent old classic from the American mineralogy. Really sharp crystals of hübnerite forming groups of parallel growths, some of them isolated. With the intense brown color and brilliance and an esthetic contrast with the snowy white matrix. Nowadays, it is very difficult to find specimens with this quality or any other quality...


Size: 8.8 x 4.5 x 3.8 mm.
Main crystal: 18 x 8 mm.

Ex. Schick collection


 

RM1809   Microcline, variety amazonite

Pikes Peak, Teller Co., Colorado, United States

Rich group of microcline crystals, amazonite variety, showing defined faces and edges and a very aerial disposition. The color is quite good and very attractive. From an old Catalan collection.


Found in ca. 1984

Col. J.M. Manchión (Barcelona). No.81, adq. C. Curto 05/1984.


 

RM1869   Baryte

Sterling Mine, Leeson Pocket, Stoneham, Weld Co., Colorado, United States

A very aesthetic cluster of prismatic, lustrous and gemmy, ice-blue baryte crystals with minor calcite from the named Leeson Pocket at the famous Stoneham locality of Colorado. The form is excellent and the largest crystals are doubly terminated. This fine piece is from the major 1989 finds and purchased to E. Kucera (Barcelona). Nearly pristine, only one crystal on the periphery is broken. An excellent specimen, uncommon in the market. A really interesting article in Rocks and Minerals available here.


Size: 6 x 3 x 2 cm.
Main crystal: 53 x 12 mm.
Found in ±1989.

Col. J.M. Manchion, Barcelona. #477, 1989 Kucera.
