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 malachite 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!!! Rich and VERY unusual, confirmed 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!!!
STAY TUNED!!! MORE AUCTIONS WILL BE ADDED SATURDAY NIGHT FOR A SPECIAL 5-DAY AUCTION, ENDING THURSDAY MARCH 28th!!!
