A very stylish 18ct white gold Art Deco ring that was most likely made in Switzerland. It is set with a good twenty five point diamond in the centre. It is surrounded by synthetic sapphires which in turn have a border of small diamonds. 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 ring is set with wonderful and very convincing synthetic sapphires. These stones were widely used in the 1920s especially in Europe between the wars. What a beautiful engagement ring this would be for the price!<\/p>\n","protected":false},"excerpt":{"rendered":"
