A beautiful 2.93 CT peach (orangey/red) colored 2.93 ct Oregon Sunstone set in sterling silver.  The setting is suspended on an 18 inch long-short chain with lobster closure.
 
The gemstone was mined in Oregon, USA.  Colored sunstones are far more rarer because most are almost clear to champagne colored. Dichronic is even rarer because it displays 2 colors, usually green and red.
