Sapphires are a form of corundum and although traditionally blue in colour, they can also be pink, yellow, purple or green. Red corundum is known as ruby.
The traditional birthstone to give as a present for September is sapphire. It is also the stone to buy for someone born on a Thursday.
Sapphires are traditionally given as a gift for 45th anniversaries.
One of the most famous sapphires is that in the engagement ring given to Lady Diana Spencer by her husband to be, Prince Charles the Prince of Wales. This ring was subsequently given to Kate Middleton when she became engaged to Prince William, the now Duke of Cambridge.
Nearly all natural sapphires are heat treated to improve their colour and clarity.
Most of the sapphire jewellery that we sell at Polkadot Stripes is created with Siberian Sapphire, which is a man-made variety with all the colour and clarity of the most expensive natural stones, but without the high price tag. Our Siberian jewellery is all rhodium-plated on silver which means that it will not tarnish if cared for properly.
