Sapphire is a stone most people are familiar with, although less people are aware that Sapphire can be found in many colours; pink, purple, yellow, lilac, green, white, black and even orange. The colour is always used as the prefix such as pink sapphire, green sapphire etc, if it is just ‘Sapphire’ it should be blue (apart from red sapphire which is a ruby, what a world!). Sapphire is made of Corundum, or aluminium oxide if you will.
Sapphire is one of the ‘precious three’ gemstones (sapphire, emerald, ruby) which are often used in jewellery due to their hardness, rarity and beauty. Sapphire scores 9 on Moh’s scale of hardness making it a popular choice for engagement rings and most jewellery.
Sapphires can be mined in Australia, Thailand, Africa, Sri Lanka and the USA among others. The blue tones range from the dark, inky blackish blue usually sourced from Australia, to the beautiful corn-flower blue of the Kashmir stones, these are by far the rarest and most valuable. Ceylon sapphires are also extremely popular, Princess Diana’s (now Kate’s) oval sapphire engagement ring is a Ceylon sapphire, a medium to strong blue with a lot of life. Sapphires have been royal stones for centuries, the British Sovereign’s ring is designed around a central sapphire and the St Edwards’s sapphire is probably the oldest stone in the British crown jewels, tests have shown this to be Ceylon in origin.
Sapphire is the birthstone for September and the Zodiac stone for Taurus. On the British anniversary gift list you’ll have to put in 45 hard years of service before you get to sapphire…my advice is it’s a fabulous gem, beautiful, durable and rare, life is short, buy your own!
