Oregon is internationally famous for its Sunstone, a feldspar mineral and a type of labradorite that contains large numbers of microscopic copper platelets that produce an interesting play of color. Named after its appearance showing array of sun like colors and shimmering sun ray like Copper Schiller.
Oregon mined gems are rarest of ALL Sunstones in the world, it's the only place worldwide producing the highest gem quality Sunstone in a wide array of truly beautiful colors, some with copper or extremely rare silver Schiller effect. Only the original Oregon sparkle with illusive pure Copper Schiller not found anywhere else on this planet. Also, all Dust Devil mine gems are substantially harder compared to any other Sunstone mined anywhere else! Sunstone from Oregon has retail value between 200 and 5,000 USD per finished carat depending on color, type of Schiller, clarity, size and quality of cut!
The least valuable form is the colorless to pale yellow followed by the pinks and tans. The most valuable and rarest color is the blue-greens, followed by the greens and reds as well as the bi-colored and tri-colored stones. Stone weighing 12 carat and above of any colors is also considered rare. The more expensive one has no schiller in it and does not colorshift. The reds with large sizes (over 3 carat) of prime color retailing at as much as $1700/ct according to Sinkankas, and at $1000/ct in Federman's book. The best greens are very rare and may cost more than the best reds.
