Ask a question

A stunning unheated cushion cut ruby is the star of this yellow gold and platinum diamond-set ring from about 1940. 

The ruby is clear and bright with an intense hue. Its square shape is continued in the diamond surround and completed by the diamond-set shoulders. 

The warmth of the 18-carat old gold complements the ruby beautifully, too. The platinum top setting is not read by the eye. Its purpose is to retain the white hue of the diamond surround. 

This would make a beautiful vintage engagement or dress ring.
