What is a garnet?

What makes garnets so wonderfully distinctive is that they’re actually a family of several closely related gemstones, each one called a species. Garnet varieties are found all over the world, most notably in India, China, Australia and the United States. The six garnet species specifically used in jewellery include almandine, spessartine, grossular, pyrope, andradite and uvarovite, the rarest garnet type — this variation is emerald green in colour and is often too small to cut. Garnet in any form is the birthstone for January.

What to Look for in Garnet Gemstones

Colour and clarity are two very important characteristics of garnets, which are available in all shapes and sizes. They’re affordable and look gorgeous with any metal or jewellery setting. Here’s what to keep an eye out for when you’re choosing a garnet.

    In most cases, the colour of a gemstone is its most important feature. Garnets come in a wide range of colours, from orangey-red to reddish-purple, with a deep, true red being the most popular. Some garnets come in colour-changing varieties, which look different under various light sources. The most desirable garnet gemstones have a pure, consistent colour throughout. Garnets with slight traces of other colours are usually more affordable but are still just as coveted and dazzling to look at.

  • CUT

    The variety of gemstone cuts showcase certain properties, such as their brilliance, colour, size or clarity. Garnets are often cut in styles that allow the gem to keep more of its weight. Popular shapes for garnets include round, oval, cushion, trillion and heart.

    Gemstone clarity refers to the number and visibility of trace materials—known as inclusions—that are present in most gemstones. Inclusions in red garnet species are usually invisible to the eye, making for clear colour and excellent irridescence. Orange garnet often has visible inclusions, typically making it a better value, but also adding to its charm.

    When shopping for gemstones, it’s best to consider the gemstone size — the diameter of the stone in millimeters — rather than the carat weight. Diameter measurements tell you how much of your colourful garnet is visible from above. Rare garnet varieties are worth more at larger sizes, but the cost of common red garnet doesn't significantly increase with the diameter of the stone.

    Enhancements improve the colour and clarity of a gemstone. Most gemstones on the market are enhanced in some way, usually with heat treatment. Garnet stands out because it's a heat-sensitive gemstone and is rarely enhanced. We offer the highest quality gemstones treated using accepted techniques.

Hardness & Wearability

Depending on the species, garnet ranges from 6.5 to 7.5 on the Mohs hardness scale, which means that it’s a durable gemstone for all styles of jewellery, as long as you treat it with proper care. Don’t let your garnet suffer hard blows or rough wear.

Choosing the Right Garnet Jewellery

With so many options available, it's easy to pick a one-of-a-kind piece of garnet jewellery to reflect your personality. Rich, deep red garnet is always a stand-out, and its high clarity further intensifies its transparency and shine. Rare purple and green garnet gemstones have the appeal of exclusivity.

In any of its colours, garnet is an ideal gemstone for earrings, bracelets, necklaces, rings or pendants. Consider which jewellery type best suits your style.
