Sylvanite and Native Tellurium Boulder Co., Colorado 7.08cm x 4.15cm x 2.85cm Ex. Ward's (c.1890's) Ex. Michigan College of Mines No. 1791 Ex. A. E. Seaman Mineral Museum #DM-20423

Description/Interesting Notes: A fantastic, old time example of sylvanite and native tellurium from Colorado!!! While old time examples of telluride species from Cripple Creek are well-known to collectors, examples of the telluride species from the Boulder localities are quite scarce by comparison!!! This specimen hosts a rich showing of silvery sylvanite and tellurium partially covering its broad face!!! The sylvanite and native tellurium are present as a brilliant, silvery network of intergrown, submillimeter crystals!!! The vein of this intergrown material is substantial, as one can see on when viewed from the side!!! This specimen is from the A.E. Seaman Mineral Museum and retains old labels from Ward's (c. 1890's) and Michigan College of Mines!!! Rare old time 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!!!
