What are sapphires?
Sapphires are one of the ‘Big Three’ gemstones, along with emeralds and rubies, and they’re naturally formed from a mineral known as corundum. Sapphires are popular for their rich colour and have been used for centuries by royalty and the wealthy, making them one of the most sought-after gemstones. These gems almost always have some form of inclusion or flaw, and if you have a completely unmarked, flawless sapphire, chances are it is synthetic. A key feature of sapphires is their colour saturation, as it’s banded it can leave colour striations – whereas in synthetic stones these are often evenly curved, from the grown crystal.
While sapphires can be found in blue, pink, green and other colours, the only colour you won’t find them in is red. This is because gemstones formed from red corundum are what we know as rubies. The trace elements in corundum crystals are what change the colour of a sapphire, changing how the light reflects and refracts. These trace minerals are naturally found in sapphires formed under the earth’s crust millions of years ago.
How are sapphires assessed for quality?
Each sapphire is evaluated in its own right, because there’s currently no global standard for assessing sapphires. In a similar way to diamonds, sapphires need to have good clarity, meaning a lack of flaws or cloudiness, and the colour must be rich, bright and vivid.
Besides the classic blue, you’ll find sapphires in a wide range of different colours. Some are commercially sold while others are rarer and as such tend to be collectable.

Blue is the classic colour that most people think of when they picture a sapphire, and it’s naturally the most common. Blue sapphires can range from light blue to a more intense blue-black hue, and they’re a favourite for earrings, pendant necklaces and alternative engagement rings.

Pink sapphires may be light pink all the way to deep fuchsia, and providing that the colour is clear and bright, all of these shades are accepted as genuine sapphire. But bear in mind that there’s a fine line when a pink sapphire crosses into red and becomes a ruby, a colour distinction that’s never been officially declared. With this in mind, if you’re buying a pink sapphire piece, it’s up to you to pick a shade you prefer. Pink sapphires are quite rare, so they can be more expensive.
This gemstone can range from a pale lemon colour to intense tangerine. Experts tend to agree that the golden-orange-coloured sapphires are the best and more desirable, but customers often choose a lighter yellow because they can make for a more affordable alternative to yellow diamonds.
From pale olive to deep bottle green, green sapphires can come in all shades, but most people who want green gemstone jewellery tend to prefer emeralds for the richer colour. Green sapphires do have an advantage over emeralds, however, as they’re harder and more durable, making them a great alternative if you want something more affordable and long-lasting.
Sapphires can also come in monochromatic tones too, and a colourless sapphire is referred to as a white sapphire. They’re one of the rarest colours of sapphire, and are often used as an accent stone in jewellery or as an alternative to diamonds.
Padparadscha is one of the rarest hues of this particular gemstone, and as such it’s one of the most expensive – often seen on the hands of the rich and famous throughout history. They’re a peachy-orange colour and the name refers to a lotus flower. They’re often sold as collector’s items due to how rare and costly they are – in fact, one of the most famous uses of this stone was in Princess Eugenie’s engagement ring.
If a sapphire isn’t blue, black or colourless, it’s referred to as a ‘fancy sapphire’ – and one of the most prominent fancy sapphires is the star sapphire. This is a unique gemstone that has a characteristic known as ‘asterism’ which is a star-light light reflection that can have a blue, black, grey, pink, white, purple or yellow body. These gems have an earthy, mysterious feel to them that suits all types of jewellery.
