This impressive French diamond ring has been crafted in platinum.

The 0.42 ct old European round cut diamond is held in relief in an eight claw, pierced decorated, elevated basket setting embellished with a fluted border.

The elevated, pierced decorated ring shoulders are acented with a subtle cuff design at junction with the platinum hallmarked shank.

The exterior of the shank is struck with the French dog's head hallmark.

This antique solitaire ring is supplied with an independent diamond grading certificate.


The diamond ring is fine quality, set with a very high colour graded and very high clarity graded old cut diamond.

This French ring is a very good gauge of platinum and is in excellent condition, the dog's head hallmark to the exterior shank shows signs of wear but remains legible.

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