Blue sapphire is a gemstone variety of the oxide mineral corundum, comprising of the two elements aluminium and oxygen, the two chemical elements required to form sapphire crystals. Blue sapphire can range in colour from very pale to very dark blue and it occurs when the crystals contain small amounts of iron and/or titanium, which act as a colouring agent.

Sapphire can also demonstrate different shades of blue/purple in natural or artificial light. These beautiful stones are called “colour-change” sapphire.
On the Mohs Scale of hardness, sapphire is rated as a 9 (as is ruby), making it second only to diamond in terms of its resistance to scratching. This is one of the reasons why it is a popular choice in jewellery that is worn regularly, such as engagement rings.
The vast majority of blue sapphires on the market today have been heat treated in some way to improve their colour and clarity. Heat treatment in a gas or electric furnace is now a standard procedure in the gem industry.

Some of the best blue sapphire in the world has originated in Ceylon (Sri Lanka) and Kashmir. The term “Kashmir Sapphire” is often applied to outstanding examples of this gemstone, even when the stone itself did not come from that region.
Ceylon / Sri Lanka has been an important source of blue sapphires for many centuries. Even today, the gemstones are mined by hand from gravel deposits that cover large parts of the southern half of the country. Blue sapphire from Sri Lanka comes in a range of stunning colours, but they are typically light-to-medium blue. Some of the largest Sri Lankan cut gemstones, such as the Logan Sapphire, weigh up to several hundred carats.
