It is difficult to get just copper chisel chips anymore. This specimen with both copper and silver is unique. As shown in the photos there is a generous amount of silver. This piece was acquired from the collection of John Perona in August of 2014. I in turn purchased it from Michigan collector, Ed Coleman, last week. It is from the Cliff Mine, Keweenaw County, Michigan.
The color in this specimen is amazing when backlit. It varies from a teal blue at either end to a blue green in the center. One end is 80% terminated while there is no termination on the other end. Although somewhat sacrilegious, I believe wonderful stones could be cut from this crystal. The specimen was originally in the collection of Michigan Collector, Robert Nowakowski. His original label is provided. The specimen comes from Coronel Murta Mine, Minas Gerais, Brazil.
Bi-colored tourmaline with 1/3 a rich green and the remaining 2/3rd’s a reddish pink. Neither end of this crystal is terminated. However, the color and transparency makes the piece. Originally in the collection of Michigan collector, Robert Nowakowski. The specimen comes from Stak Nala, Skardu, Pakistan.
A large tanzanite crystal measuring 6.5cm in length and 3.8 cm in width! The color ranges from a deep translucent blue in the center/bottom of the crystal to a combination blue and white around the balance of the crystal. A clear 1.2 cm quartz crystal sitting on the front edge of the tanzanite crystal provides added aesthetics. This specimen is from Merelani Hills, Lelatema Mts., Simanjro District, Manyara Region, Tanzania.
