Edwardian Platinum Diamond & Opal Pendant on Platinum Chain

A stunning platinum pendant on a platinum chain. It is top quality and set with a large oval opal which is very lively and displays blue, green and red flashes. It is surrounded by twenty four bright white diamonds in millgrain settings. This is an extra detail which makes an antique piece special. It is created with a knurling tool which was used to create small balls of platinum around the edge of the stones. The reverse is equally as detailed with hand finished decoration. It was made circa 1910-1920.
