Gatsby Jewellery Ltd has dated this piece to the 1960s.
The stone is set in an open four-claw V collet, designed to allow as much light to pass through this rare white stone as possible. A baguette cut diamond is set in each shoulder, with an eight-cut diamond set ribbon appearing to thread through the top of the ring.

Because of its unusual profile the engagement ring comes with a later crafted wedding band which stacks neatly against it. Set with seventeen round brilliant cut diamonds in platinum.
Accompanied by a Natural Diamond Grading Report from HRD Antwerp (#210000182315).
