THE STORY: 
Certificate from Bellerophon Gemlab located on Place Vendome in Paris - one of the most prestigious locations, where the super-luxurious jewelry companies are to be found.

Even when luxury jewelry was made in gold during previous centuries, diamonds were invariably set in silver (later in platinum or white gold). It was considered that the white metal showed diamonds off to better effect in gas or candle light.

This ring is made in the same, classic style as the famous blue sapphire engagement ring of Princess Dianna. (Sapphire surrounded by a ring of diamonds).
