FAQ — Your Questions About White Sapphire
What exactly is a white sapphire?
White sapphire, also known as leucosapphire, is a colourless variety of corundum, the same mineral that produces blue sapphire and ruby. It is the official birthstone for April.
What is the difference between a white sapphire and a diamond?
Although they may look similar, white sapphire and diamond are two completely different minerals. Diamond is composed of pure carbon and has a hardness rating of 10 on the Mohs scale, whereas white sapphire is made of aluminium oxide and has a hardness rating of 9. Diamond also displays greater fire and light dispersion, but white sapphire remains an elegant and significantly more affordable alternative.
Is white sapphire a precious or semi-precious gemstone?
Traditionally, only diamond, ruby, sapphire and emerald are classified as precious gemstones. As a variety of sapphire, white sapphire therefore belongs to this category, unlike many gemstones described as fine or semi-precious stones.
How much does a white sapphire cost?
The price of a white sapphire varies according to its transparency, clarity, cut and carat weight. It is generally much more affordable than a diamond of comparable quality and carat weight, making it a popular choice for engagement rings.
How can you recognise a high-quality white sapphire?
A high-quality white sapphire should have excellent transparency, very few inclusions visible to the naked eye and a cut that maximises its brilliance. The gemstone’s origin can also be an important indicator of quality, with Sri Lankan white sapphires being particularly prized by connoisseurs.
Can white sapphire replace a diamond in an engagement ring?
Yes. White sapphire is now one of the most popular diamond alternatives for engagement rings thanks to its exceptional hardness, transparency and more accessible price.
How should you care for white sapphire jewellery?
Thanks to its exceptional hardness, white sapphire can generally withstand steam and ultrasonic cleaning. However, prolonged contact with harsh chemicals should be avoided, as these substances may gradually dull its brilliance.
