亞歷山大變色貓眼石配鑽石戒指

• 9顆天然「巴西」亞歷山大變色貓眼石共重約9.15卡拉
• 鉑金鑲嵌

Colour and Clarity: According to the Gubelin report, the cat's-eye alexandrite is of Brazilian origin, with no indications of treatment, with a distinct colour-change from bluish green in daylight to purple in incandenscent light, combined with a well-centered and pronounced chatoyancy. Please refer to the report for details. In our opinion, there are some natural pinpoints, fingerprint and feather inclusions under 10x loupe but not noticeable to naked eyes, and the chatoyancy is distinct. The rose-cut alexandrites are generally clean with a few minor natural inclusions and pronounced colour change from bluish-green to purple. The diamonds are about G-H colours, VS2-SI1 clarity. Condition: In mint condition.
In response to your inquiry, we are pleased to provide you with a general report of the condition of the property described above.
