In good condition, with light indentations to the mounting commensurate with wear. Inscribed PT950 750 for platinum and 18 karat gold. Also inscribed 15.20 referring to the carat weight of the emerald. The shield-shaped diamonds weighing a total of approximately 2.50 carats are approximately F-G color, VS clarity. The emerald is bluish green, vividly saturated, with light to moderate inclusions including fingerprints and feathers, some lightly surface reaching, predominantly to the girdle where a small chip can also be found under close inspection. Accompanied by AGL report no. 1096695 dated October 25, 2018 stating that the emerald is of Colombian origin, clarity enhancement: insignificant to minor, type: modern. The ring fits like a 5¾ due to the sizing beads and would fit more like a 6 if they were removed.

Our presale estimates reflect this assumption.Certificates of Authenticity: Various manufacturers may not issue certificates of authenticity upon request. Sotheby's is not under an obligation to furnish the purchaser with a certificate of authenticity from the manufacturer at any time.
