This fine and impressive vintage dress ring has been crafted in 18 ct yellow gold.

The feature cabochon opal is displayed in relief to the centre of the 18ct white gold boat style setting.

A total of thirty-two, well colour matched, modern brilliant round cut diamonds are individually claw set within two stepped borders encircling the impressive natural opal.

The elevated, tapering, pierced decorated ring shoulders integrate in to the claw setting and blend seamlessly with the plain 18ct yellow gold fully hallmarked ring shank.

The hallmarks to the interior of the shank include the gold guarantee mark (crown), 18ct fineness mark (750), London Assay Office hallmark (leopard's head), the maker's mark (ff) and the date letter mark for 1976 (B).

This impressive vintage 1970's cabochon opal ring is supplied with an independent diamond grading report card.

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.
