| Wyoming Jade |
|
Nephrite jade (also known as “Wyoming Jade”), the Wyoming State Gemstone, was
first described in the Granite Mountains area of central Wyoming in 1936
(Sinkankas, 1959; Sutherland, 1990). The most intense jade exploration and
mining activity occurred there between about 1940 and 1960 (Madsen, 1978).
Recent exploration activity indicates renewed interest in Wyoming Jade.

Diamond, composed of pure carbon, is the hardest naturally occurring mineral
found on earth. Diamonds form under extreme pressure and high temperature deep
within the earth’s mantle. They arrive at the surface through volcanic processes
that carry them upward in rare magmas (melted rocks) known as kimberlites or
lamproites. Click here for more information
