3.72ct Diamond and Platinum Trilogy Ring - Antique Circa 1920


This stunning, fine and impressive antique diamond trilogy ring has been crafted in platinum.

The pierced decorated, basket style settings display a central 1.67ct Old European cut diamond, flanked on either side by a slightly smaller 1.10ct and 0.95ct Old European round cut diamond to complete the trilogy arrangement.

The pierced decorated, elevated and tapering ring shoulders integrate with the claw settings and join the shank at a subtle cuff design.

The plain shank is hallmarked to the interior with the mark for platinum (PLAT).

This antique 1920's dress ring is supplied with three independent diamond grading certificates.

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.
