Gatsby Jewellery Ltd has dated this piece to the 1950s.
The stone is secured by six split claws in a platinum collet. Slim, spear-shaped shoulders are set with six (three each side) eight-cut diamonds, leading to a slender platinum shank.
Although De Beers have described the cut as Round Brilliant, the diamond has many characteristics of an Old European Cut - slightly smaller table, cut culet, burnished girdle - making this a transitional cut (a very rare cut that bridged old European cut and round brilliant) rather than a modern round brilliant.
Accompanied by a De Beers Institute of Diamonds grading report. A unique number has been inscribed on this diamond providing utmost security.
