Condition
Colour and Clarity: According to both GRS report, the cabochon star colour-changing sapphire is natural, of Ceylon origin, with no indication of thermal treatment. Please refer to the report for details. In our opinion, the star sapphire shows a distinct colour-change effect, from purple under incandescent light to medium blue hue upon daylight, with a fine six-ray star under spot lighting. There are many fine silks and a few crystal inclusions under 10x loupe check, not seen to naked eyes. Diamonds are about F to G colours, VS clarity.
Condition: Karat white gold ring mount, in very good condition.
