Gem of the Sky

The ancient Persians believed that the sky was a huge sapphire into which the Earth was embedded.

When thinking of sapphire, what likely comes to mind is an image of a deep blue gemstone. Although sapphires are often a beautiful blue colour, sapphires can also be yellow, green, white, colourless, pink, orange, brown or purple.

Sapphire is never red as a red sapphire would in fact be a ruby. Sapphire and ruby are the same mineral, corundum. It is the presence of small amounts of other elements such as iron or chrome which gives sapphires (or rubies) their colour.

Sapphires that are not blue are described as “fancy sapphires”. The most coveted of the fancy sapphires are the padparadscha sapphires, which are found mostly in Sri Lanka. It is a stone with a pink-orange colour.

The value of a sapphire depends on its size, colour and transparency. The best sapphires have a rich, translucent colour. The most valuable colour is a cornflower blue. Sapphire is commonly heat treated to improve the stone’s colour. Heat treated stones do not have as much value as a natural stone of comparable colour.

Sapphire is the second hardest mineral, after diamond. It is a 9 on Moh’s scale of hardness. The hardness of the stone makes it easy to look after and makes sapphire an ideal choice for all types of jewelry, including items that typically take more abuse, such as rings and bracelets.

In ancient times, a gift of sapphire was considered to be a pledge of trust, honesty, purity and loyalty. This tradition is in part the reason that sapphire remains a popular choice for engagement rings.

Sapphire is the birthstone for the month of September.
