For centuries and to the present, jewellers have been trying to perfect the artificial gemstone. It wasn’t until the 19th century that great progress was made, with one of the first grown in a laboratory being a sapphire. In the age of man versus machine, Art Deco was a great period that showcases these artificial gemstones in jewellery. This sublime Art Deco ring is a perfect example of old cut diamonds being highlighted by synthetic sapphires. Although these sapphires are ‘man made’, it is non-the-less a true stone as fine powdered chemicals are melted under high temperature to produce a synthetic crystal. Not only were they praised for their beauty but also for the ability of the jeweller to colour match and pare multiple stones. Antique jewellery with accent stones does not necessarily devalue the piece but in actual fact, a useful way to determine its’ age and provenance.
