Synthetic sapphires were extensively used during the Art Deco period from when this ring dates to. Synthetic sapphires were created by a French chemist Auguste Verneuill in 1909. Synthetic sapphire have the same chemical properties as a natural sapphire. They have equal hardness and density and look the same as natural sapphires but without any flaws.

The finest sapphires were mined in Kashmir region of India and are a very pretty velvety blue. These Kashmir minds are now exhausted, so antique stone are prized not just for beautiful colour but also for their rarity. Burmese sapphires are now also rare and also expensive, Burmese sapphires are a deeper richer blue than the Kashmir stones.
