Howardite aka Rattlesnake Jasper designer gem 4/22/2018 01 -
33 x 20 x 4.1 mm - 18 carats - This unusual cab is cut from
one of the most rare and sought after semi-precious stones
in the world. The material is said to be an agatized/silicified/opalized
tuff of which the location of the deposit is apparently lost
or mined out, nobody seems to know exactly. It has been
thought to come from northern Nevada. John Sinkankas
mentioned in the book "Gemstones of North America" (1959)
that this material was more like chert and that it came from
California (shown in a photo with other California agates).
Regardless of locality it is some of the rarest lapidary
materials available. This wonderful designer paisley drop
gem sports a beautiful low dome, girdled sides and a flat
beveled back all with high gloss luster. There are some
druzy surface voids that do not detract from the quality or
beauty of the stone. This stone's colorful patterns
suspended in nearly transparent agate make it distinctive
and unique. This is a very rare, high grade cab of this
illusive stone. Here is a video clip to see the stone in
motion:
