Synthetic Corundum: Synthetic Ruby


Synthetic ruby stones are created in laboratories using the flame fusion method and has the same properties and chemical structure as naturally occurring ruby. Strong magnification is usually required to distinguish between the natural and synthetic rubies. In 1902, the French chemist, Auguste Verneuil, developed the Verneuil process (flame fusion method) in order to grow synthetic rubies. The method is still in use today and is also used to grow other synthetic stones.

Synthetic ruby is the red variety of the mineral species, corundum. The red colour is the result of traces of chromium. All other colours of corundum are referred to as synthetic sapphires.


Rated 9 on the Mohs scale of hardness, synthetic ruby is harder than all other stones except the diamond. This, combined with excellent toughness, makes it very durable and ideal for all types and styles of jewellery.

The natural ruby is the world’s most celebrated red gemstone and is revered in ancient Sanskrit writings as the most precious of all gemstones. Natural rubies have adorned emperors and kings and have inspired countless legends with their rich, fiery hues. The intense red colour was thought to come from an undying flame inside the stone or believed to be a piece of the planet Mars. It is a favourite stone among those in power and in love, as it is considered the gem of courage, passion, desire and emotion. This is why a natural ruby is often given as a token of passionate love and romance. The stone has also been used as a talisman against danger and disaster, and for treating a number of ailments.
