I describe this color as Dark Peach or Light Reddish Orange, however it does flash from lighter to darker shades of peach to orange as the gem is rotated.
There is no eye visible Schiller effect.
This Sunstone is a faceted round, 3.62 carats (scales can vary so this is always an estimate) and measures approx. 10.0 mm (rounded up or down to nearest whole number).
