Description/Interesting Notes:
A very unusual example of sylvanite and coloradoite from Montana!!! This specimen hosts a rich showing of
silvery metallic sylvanite and coloradoite intergrown with chrysocolla!! The sylvanite
and coloradoite both have distinctly different hues in person - with the sylvanite having a much warmer,
silvery hue whereas the coloradoite has a much more slate-gray silvery hue!!! Upon close inspection it
appears that the sylvanite and coloradoite are almost suspended in a chrysocolla-like silicaceous
substrate!!! I have never seen anything like this material - it is almost like microscopic grains
are distributed throughout thin layers of chrysocolla (it originally came from David New to Tony
Nikischer and had a note that it was ID'd by Sid Williams)!!! Rich and VERY unusual material!!!
The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
Good luck and be sure to check out my other exciting mineral auctions on ebay!!!
