Sunstone (feldspar) from this gem field comes in a variety of colors. Most common is a light straw-yellow. The color most highly prized is the deeply saturated reddish-orange sunstone (Hence the name "Sunstone). The reddish color is a result of trace amounts of copper. When the copper is present as tiny platelets, light can reflect from the surface of the platelets and cause an iridescence termed "Schiller." This gem has several wisps of Schiller running from top to bottom and oriented perpendicular to the table of the gem. Examined carefully the gem looks like it contains a tiny interal aurora borealis. The body color of this expertly crafted gem is a fine reddish-orange. This beautiful stone would be perfect as the centerpiece of a pendant, pin, or occasional-use ring.
