Bicolor concave cut 3.85ct Oregon Sunstone

This  stone originated at the Sunstone Butte mine. 
This higher elevation mine (about 15 miles from the Sunstone Collection area) has an abundance of darker colored greens and bicolor Oregon Sunstones. 
This one is cut in a rectangle with concave cuts on the sides to give it extra refraction. Photos just don't do this stone justice. 
The stone weighs 3.85ct and measures 7.8x12mm.
