Description/Interesting Notes:
A fantastic, old time example of coloradoite from the type locality in Colorado!!! This specimen hosts a rich showing of
this rare mercury telluride in association with a small amount of sylvanite and likely empressite (among other possible rare species)!!!
The matrix hosts numerous parallel cavities in matrix that have been partially filled with silvery gray coloradoite!!! Upon close inspection with a loupe or scope one
can see a few tiny, sharply formed crystals of sylvanite present as well as a few tiny, submillimeter crystals of native gold!!! There are also
dark gray areas of likely empressite and areas of other rare species that are characteristic of this locality!!! There is a lot going on on this specimen
and there is a lot to see upon close examination with a loupe or scope!!! This specimen is from the A.E. Seaman Mineral Museum,
University of Pennsylvania, and G.A. Koenig (1844-1913) Collections!!! This specimen retains old labels from the Seaman Museum and
University of Pennsylvania/G.A. Koenig!!! Rare, old time material!!!
The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
