Blue, and much more

The blue colour of sapphire comes from small amounts of iron and titanium. Sapphires in other colours are known as fancy sapphires. A special one is the padparadscha, a rare pinkish-orange sapphire.

Sapphire in vintage jewellery

Sapphire is a classic in vintage rings. You often see it at the centre of a cluster ring, with a border of small diamonds around the centre stone. Sapphire was also widely used in Art Deco jewellery, sometimes in small, calibré-cut pieces set between diamonds.

Sapphire for everyday wear

With a hardness of 9 on the Mohs scale, sapphire, like ruby, is extremely scratch-resistant. That is why it is a popular choice for engagement rings. You can read more about the stone on our sapphire page.
