Sapphires (Corundum) can be mesmerising with beautiful deep royal blues to vibrant pinks, yellows, greens, purples and orange colours with lots inbetween such as bicolour stones which can be blue in one light and purple in another. Major sources of sapphire are SriLanka, Burma, Thailand, Cambodia, Madagascar, Tanzania and Australia. Typically found in igneous rocks large crystals of minerals formed as they cooled down and the more slowly the magma cooled the larger the sapphires would be.
The different colours are created when different mineral concentrations are present in the rocks. The presence of iron makes the sapphire take on a yellow colour whilst Vanadium makes them purple and Titanium for blue stones. No two sapphires are the same, each stone having its own natural fingerprint. Most sapphires have natural inclusions within them – indeed sapphires without inclusions are extremely rare and valuable.
Heat treatment is applied to most Sapphires to improve colour – it is permanent and a traditional treatment in the industry. Unheated stones (i.e. totally natural) tend to be much more expensive than heat treated ones and are normally certified as ‘natural unheated Sapphire’.
Sapphire is extremely hard as a gemstone at 9 on the MOH scale which makes it ideal for a dress or engagement ring where considerable wear is anticipated.
Sapphire mining in areas like Sri Lanka and Madagascar is largely open cast in pits where the miners just dig down to expose the gem bearing rocks whilst larger deeper mines can be found in places like Australia and Thailand.
