0.62ct Aquamarine and 0.69ct Diamond, 18 ct Yellow Gold Twist Ring - Antique Circa 1900


This stunning, fine and impressive aquamarine and diamond ring has been crafted in 18 ct yellow gold, with 18ct white gold settings.

The twist design is ornamented with a feature 0.56 ct Old European round cut diamond and a 0.62 ct round faceted cut aquamarine, individually eight claw set in 18 ct yellow gold.

The subtly flared twist design ring shoulders of this stunning ring are ornamented with a total of six pavé set Dutch cut diamonds graduating in size.

The ring shoulders integrate with the twist design and meld seamlessly with the plain ring shank.

This antique aquamarine and diamond twist ring is supplied with an independent diamond grading certificate for the feature diamond, in addition to an independent diamond grading report card for the aquamarine and supporting stones.

The outer surface of the ring shank is hallmarked with the French limited/restricted warranty mark (horse head), incorporating the assay office mark for Bayonne (∑); this hallmark determines the piece as 18ct gold.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.
