Sunstone from Lakeview (Plush), Oregon

No. 891: Pendeloque Cut, 4.42 ct., 16.1 x 9.4 x 7.3 mm, SI2, faceted by Robert Drummond, $198.90 Sold

Sunstone (feldspar) from this gem field comes in a variety of colors. Most common is a light straw-yellow color. Most highly prized is 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 gemstone contains many layers of fine copper platelets located throughout the stone. The color of this gem is an unusual salmon-orange color with a shimmering glow. The facet meets, proprotion, and polish are all good. This gem would look great in a pendant, pin, or special occasion ring. This is definitely a gemstone for the person desiring something rare and very special.
