Sapphire - September’s Birthstone

Sapphires are a beautiful choice for engagement rings & the birthstone of September

The birthstone of September is sapphire - a beautiful gemstone that's a variety of the mineral corundum. The most popular colour sapphire is blue, but sapphires form in a wide range of colours (aside from red - this is a ruby). From yellow to pink and purple, every sapphire that forms is unique. 

September's birthstone is the sapphire-a precious gemstone of that, according to ancient lore, instilled wisdom, loyalty and nobility. When used in engagement rings, sapphires symbolise faithfulness and sincerity. 

Where are Sapphires Formed?

Sapphire deposits can be found in North America, East Africa, Thailand, China, Montana, Madagascar, Sri Lanka and Eastern Australia. What's interesting about Sapphires is that their origin doesn't guarantee the quality, as each mine produces large quantities.

Tips for buying Sapphires

Treated Sapphires 

Whether you're buying loose sapphires or sapphires for jewellery, there's a strong chance it has been treated. In order to get rid of tiny inclusions and impurities, sapphires undergo intense heat treatments, thus enhancing the colour and reducing the opacity of the jewel. 

As with any gemstone, whether it is a diamond, ruby, emerald or sapphire, you should ask which method has been used to treat it. In the GIA Identification Report, you can find out whether the gem is synthetic, natural or has been treated in any way.
