Description
- cat's-eye alexandrite, diamond, platinum
Centring on a cabochon cat's-eye alexandrite weighing 5.10 carats, surrounded by brilliant-cut diamonds extending to the shoulders together weighing approximately 3.65 carats, mounted in platinum. Ring size: 6¼
Condition
Colour and Clarity: According to the Gubelin report, the cat's eye alexandrite is of Brazilian origin, with no indications of treatment, distinct colour-change and well-centered and pronounced chatoyancy. Please refer to the report for details. In our opinion, the alexandrite is of greenish blue in daylight and purple in incandescent light, with a distinct chatoyancy that appears open and close as stone is rotated. Under strong penlight, there are some natural fissures that are not noticeable to naked eyes. The diamonds are about F-G colours, VS clarity.
Condition: In mint condition.
