1.71ct Diamond and Platinum Trilogy Ring - Antique Circa 1920


This fine and impressive 1920's trilogy diamond ring has been crafted in platinum.

The pierced decorated setting displays a feature 0.66ct Old European round cut diamond, claw set to the centre of the arrangement.

The feature diamond is flanked on either side by a slightly smaller Old European round cut diamond, both claw set.

The elevated, tapering ring shoulders integrate with the main setting and blend seamlessly with the plain ring shank.

This three stone diamond engagement ring has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

The ring is supplied with an independent diamond grading certificate for the feature diamond in addition to an independent diamond grading report card for the supporting stones.

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.
