The collet-set brilliant-cut diamond enhanced by a two-tone wide band, mounted in yellow and white gold,

Stamped 750 for 18 kt white and yellow gold. The estimated weight of brilliant-cut diamond approximately 13.00-13.10 carats, in our experts' opinion the diamond is P-Q colour, VS1 clarity, with faint white fluorescence. Colour and clarity graded as far as the yellow gold collet-set mounting will permit. Signs of wear to band and around collet setting consistent with wear. May benefit from re-polishing.
