September Birthstone: Sapphire


Treasured as one of Earth’s most precious gemstones, in ancient times the sapphire was believed to protect the wearer from evil. Today, September’s birthstone continues to capture hearts with its dazzling beauty.

Brilliant and timeless, the sapphire is the traditional birthstone for September. It is said this much-loved stone represents loyalty, fidelity and truth, making it a popular choice for engagement rings.

But there is so much more to September’s birthstone than simply being the world’s most popular blue gem.

A sapphire’s true colours

Commonly known as an iconic blue stone, sapphires in fact come in almost every colour of the rainbow.

Like rubies, sapphires are a member of the corundum family. Although sapphire is generally thought of as blue, pure corundum (aluminium oxide) is in fact colourless. Deep blue sapphires contain iron and titanium, while gem-quality red corundum is better known as ruby. Gem-quality corundum stones of any other hue are considered sapphire, but violet shades are particularly sought after.

Together, iron and titanium create the blue colour that sapphires are best known for. However, iron can also give the corundum a yellow or green colour. Trace elements of chromium can even create a rare pink sapphire. These stunningly feminine stones have been famously worn by Grace Kelly and Queen Elizabeth II.

As well as lustrous beauty, the sapphire has exceptional hardness and durability. This, along with its rarity and brilliance, makes it the perfect jewellery stone. On the Mohs scale of hardness, it is rated a 9, second to diamond in its resistance to scratching.

Loved throughout the ages

Desired by royalty and coveted by civilisations for millennia, sapphires are prized precious gems, which can take millions, and sometimes billions, of years to form. Popular in ancient Rome, ancient Persia and throughout the Middle Ages, the sapphire has never lost its high status.

The word sapphire derives from the Latin and Greek words for blue, the vivid hue that the September birthstone is known for.

This dazzling gemstone has been associated with myth and legend throughout human history and was once believed by Ancient Persians to be the treasure of the world.

French Emperor Napoleon Bonaparte presented his beloved wife with a two-stone blue sapphire and diamond engagement ring in 1796. With opposing tear shaped jewels, the gold engagement ring is now said to be worth $20,000 at auction.

In the 1980s, the royal blue stone became one of the most iconic gems of an era when Princess Diana chose a engagement ring featuring a 12-carat oval sapphire.

Supporting wellbeing and calming the mind

Sapphires were once used to protect the wearer by boosting the immune system. They were said to calm overactive body systems, treat disorders of the blood and regulate glands.

Blue sapphire was thought to increase the lifespan, and end headaches, nightmares and nosebleeds when placed on the forehead.

Spiritually, sapphires are known as the stones of wisdom and serenity, facilitating meditation and calming the mind.

Believed by some to keep thoughts pure and heavenly, sapphires have been worn and gifted for many reasons.

The most stunning celebrity sapphire rings

Given their enduring popularity, it is no surprise that so many celebrities have rocked the sapphire engagement ring. Charming, elegant and always a showstopper, the sapphire has been worn by royalty and celebrities for centuries.
