Garnet Jewellery: January's Stone Beyond Deep Red
Garnet is the January birthstone, and most people picture one colour: deep wine red. That red is beautiful and affordable, but it is only part of the story. Garnet is actually a whole family of stones that comes in orange, green, and more, and it has a quiet advantage over many coloured gems: it is usually completely natural, with no treatment at all. Here is how to buy it well.
We set garnet in rings and pendants at our Coquitlam bench, especially for January birthdays. It is an underrated stone that gives you rich colour for very little money.
Not one stone, but a family
Garnet is a group of closely related minerals rather than a single gem, which is why it comes in so many colours. The familiar deep red comes mostly from almandine and pyrope garnets. But the family also includes bright orange spessartine, and the rare, valuable greens, tsavorite and demantoid. Across the group, garnet rates roughly 6.5 to 7.5 on the Mohs hardness scale, according to the GIA, depending on the type. That is a fair bit of variety, so it helps to know which garnet you are looking at.
Usually natural, which is rare
Here is garnet's best-kept secret. While most coloured stones on the market are treated in some way, garnet is typically not treated at all, as the GIA notes. The colour you see is the colour the earth made. For a buyer who likes the idea of an untreated, natural stone, that is a genuine selling point, and it is unusual at garnet's affordable price.

Everyday wear and care
At 6.5 to 7.5, garnet is hard enough for regular jewellery. It is a good, wearable stone for rings, earrings, and pendants, though like anything softer than sapphire it appreciates a setting that gives it a little protection in a ring worn every day. Clean it with warm water, a drop of mild soap, and a soft brush. Most red garnets handle an ultrasonic cleaner, but the greens, demantoid especially, can have inclusions that make ultrasonic risky, so hand cleaning is the safe default, as the GIA care guidance advises. Our general jewellery cleaning guide covers the gentle routine.
Who garnet suits
Red garnet suits anyone who wants a rich, warm stone at a friendly price, and it is a natural January birthstone gift. It looks handsome in yellow gold, which echoes its warmth, and striking in white metals for contrast. If you want something more unexpected, the orange and green garnets bring the same durability with a rarer look and, in the case of the greens, a much higher price. Whichever you choose, garnet is one of the honest bargains in coloured stones, natural and rich for very little outlay. If you are collecting birthstones, it sits alongside our February amethyst and March aquamarine guides.

Frequently Asked Questions
What colour is garnet?
Most often deep red, but garnet comes in many colours because it is a family of related minerals. Besides the classic wine red, there are orange garnets (spessartine) and rare, prized greens (tsavorite and demantoid). Red is by far the most common and affordable.
Is garnet hard enough for a ring?
Yes. Garnet is about 6.5 to 7.5 on the Mohs hardness scale, which is fine for rings, earrings, and pendants. In a ring worn every day, a slightly protective setting helps, since garnet is softer than sapphire. For most wearers it holds up well.
Is garnet treated?
Usually not. Garnet is one of the few coloured stones that is typically sold with no treatment at all, so its colour is entirely natural. That makes it appealing to buyers who prefer an untreated stone, and it is unusual to find at garnet's low price.
What month is garnet the birthstone for?
January. Garnet is the modern January birthstone, which makes its rich red a popular winter birthday gift. Its long history and deep colour have kept it a favourite for centuries.
