Amethyst Jewellery Guide - Colour, Durability & How to Spot the Real Thing
Amethyst is probably the most recognisable coloured gemstone after diamond - which also means it’s one of the most imitated. If you’re shopping for a piece, here’s what’s actually worth knowing before you buy.
(Looking for amethyst specifically as a February birthstone gift? See our February birthstone guide for that angle. This guide covers the stone itself.
What Amethyst Actually Is
Amethyst is a purple variety of quartz, and its colour comes from trace amounts of iron within the crystal structure, combined with natural irradiation deep in the earth over millions of years. That’s why the same stone can show real colour variation from one angle to another - true amethyst is rarely one flat, uniform shade throughout.
Colour runs from pale lilac through to deep, almost reddish-purple - historically, the richest tones were reserved for royalty and clergy, which is part of why the stone still reads as a little more “special occasion” than some other purple gemstones.
Is Amethyst Durable Enough for Everyday Wear?
Yes - amethyst is one of the more practical coloured gemstones for daily wear. It sits at 7 on the Mohs hardness scale, the same as most quartz varieties, which puts it comfortably above many other coloured stones and makes it suitable for rings you wear regularly, not just occasional pieces.
It has no cleavage (the tendency to split along a plane under pressure), which adds to its resilience in everyday settings like rings and bracelets. That said, “durable” doesn’t mean indestructible - a hard knock can still chip or fracture any gemstone, amethyst included.
How to Spot Genuine Amethyst
Because it’s so popular, amethyst is also widely faked with glass, dyed quartz, or synthetic lab-grown material. A few things to look for:
• Uneven colour is a good sign, not a flaw. Natural amethyst typically shows gradual colour zoning - subtle variation across the stone - rather than one perfectly flat shade throughout.
• Check under different light. Natural amethyst often shows a slight shift in colour intensity depending on the angle it’s viewed from.
• Ask about sourcing. A seller who can’t or won’t tell you where a stone came from, or whether it’s natural versus lab-created, is worth being cautious with.
Every amethyst piece we sell is genuine and fully appraised before listing - if you’re ever unsure about a specific piece, just ask us directly.
Caring for Your Amethyst Jewellery
Amethyst is relatively low-maintenance for a coloured gemstone, but it’s still worth handling with care:
1. Clean with warm water, mild soap, and a soft brush. This is the safest method and works for both the stone and the silver setting.
2. Avoid extreme heat. Amethyst is heat-sensitive - prolonged high temperatures can fade or alter its colour, occasionally shifting it toward yellow or brown.
3. Keep it out of strong, direct sunlight for extended periods, as this can also cause fading over time.
4. Store it separately from harder stones like sapphire or diamond to avoid surface scratches.
5. Remove it before anything strenuous - gardening, sports, heavy cleaning - to protect against knocks.
