2.5ct Oregon Sunstone with red center spot
This oval Oregon Sunstone to me is reminiscent of a rising sun, much like the Japanese flag. That prominent red spot in the center, surrounded by a field of light champagne and almost a blueish tint are spectacular.
This is one very clean stone with no visible copper schiller.
The weight is 2.5ct and it measures 10x8mm. Would be easy to put in a pre-made setting.
