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 and minor azurite!! 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!!!
