Silver & Blue Synthetic Sapphire Cufflinks

885G
359 Admirers Rare Find

Apparently these cufflinks were made by Mr McLellan for his son. He was second in command to Barnes Wallace in designing the bouncing bomb in World War Two. He cut the synthetic sapphires. In 1902 the French chemist Auguste Verneuil developed a process for producing synthetic sapphire crystals. In the Verneuil process, named after him, fine alumina powder is added to an oxyhydrogen flame, and this is directed downward against a mantle. The alumina in the flame is slowly deposited, creating a teardrop shaped “boule” of sapphire material. Artificial sapphire material is identical to natural sapphire, except it can be made without the flaws. They are amazing to look at as the colour is such an incredible deep blue.
