CAT'S-EYE CHRYSOBERYL AND DIAMOND RING

Centring on a cabochon cat's-eye chrysoberyl weighing 18.18 carats, to a stylised mount decorated by brilliant-cut diamonds, mounted in 18 karat yellow gold. Ring size: 5½

Colour and Clarity: According to GRS report, the cat's-eye chrysoberyl is natural, of Ceylon origin, with no indication of treatments. Please refer to the report for details. This cat's-eye chrysoberyl has been repolished; a previous Gübelin report indicates that this cat's-eye was weighing 18.55 carats before repolish. In our opinion, the cat's-eye is of medium deep, orangy brown colour, with a distinct chatoyant line upon spot lighting. Upon 10x loupe and illumination, there are a few tiny crystal inclusions, not seen to naked eyes. Diamonds together weighing approximately 0.90 carat, are about I to J colours, VS clarity. Condition: Karat gold ring mount, in very good condition.
