French Art Deco Synthetic Sapphire & Diamond Cluster Ring

Rare Find
417 Admirers

I am fascinated by synthetic stones as the process is brilliant and complex. The Parisian chemist Auguste Verneuil collaborated with Fremy on developing the method, but soon went on to independently develop the flame fusion process, which would eventually come to bear his name. In 1909, Vernueil realised that synthetic sapphires could be created with the addition of iron and titanium and in 1911, he and his employer, the Heller Company, were given two patents for this discovery. So this beautifully made platinum ring is set with a wonderful and very convincing sapphire which is synthetic but looks like a Kashmir sapphire. It is surrounded by good white and well matched diamonds with a small diamond on each shoulder. These stones were widely used in the 1920s especially in France. What a beautiful engagement ring this would be for the price!
