Exceptional Native Leaf Silver with Safflorite and Skutterudite from the Cobalt Mining District!
This is an amazing Silver - Easily one of the finest Cobalt specimens I've ever seen and I acquired
it for the website the moment it was offered to me. Atop the white matrix you have a beautiful display
of numerous lustrous Native Leaf Silvers, all standing upright, with grayish Safflorite crystal clusters
and Skutterudite nestled between. The leaves average around 2 cm in size and the visual display of
the specimen is very 3-dimensional. In excellent condition and very, very impressive! The Castle Mine
is a Silver Mine just west of Cobalt which has produced since 1917. It produced 6.5 million ounces of
Silver and 300,000 lbs of Cobalt by the end of 1931. The mine opened and closed again in the 1980's.
Mindat.org displays only a handful of photos for the locality with none being as impressive as this one.

Super aesthetic plate featuring Scheelite crystals with Fluorite on Muscovite!
This is great looking specimen. The two Scheelites are well matched, highly lustrous, and gemmy
to translucent. The Fluorite cube is also well matched to the Scheelites, measuring 2.1 cm to the
2.1 cm and 2.3 cm Scheelites crystals. The specimen is in excellent condition and all three crystals
are complete. Just beneath the transparent Fluorite cube is a partial crystal of Fluorite which was
contacted along the trimming edge but this is of little importance to the specimen. Fine Scheelite
with Fluorite combo pieces are almost impossible to find these days and rarely appear at the shows.

entire length. This a specimen from the classic Cobalt Mining District and the weight is quite

layers of Native Silver inside the Calcite seam along with some associated Acanthite and Quartz
crystals. I also see some rainbow iridescence atop the Native Silver. This specimen is super rich!
