SOLD - 1.42 ct Diamond and Platinum Trilogy Ring - Antique French Circa 1930


This fine and impressive antique French diamond ring has been crafted in platinum.

The pierced decorated, geometric frame displays a central four claw set 0.72 ct Old European cut diamond in relief, flanked by a 0.36 ct and a 0.34 ct Old European cut diamond.

The elevated, pierced decorated subtly flared ring shoulders blend seamlessly with the plain hallmarked ring shank.

The ring is hallmarked to the interior of the shank with the French 18ct gold fineness mark  (dog's head).

This 1930's trilogy 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.


This original antique dress ring is fine quality set with very high colour graded, old cut diamonds.

The ring is a very good gauge of platinum and is in excellent condition with a clear hallmark to the interior of the ring shank.

Reflections in photographs may detract from the true representation of this fine example of antique jewellery/estate jewelry.
