Two numbers, one question: how much gold are you actually wearing? How to read karat and hallmark, and how to choose what suits you.
Atelier TOV5 min readUpdated 11 November 2026
14 karat gold is 58.5% pure gold and carries the hallmark 585. 18 karat is 75% gold and carries the hallmark 750. 18 karat is a deeper yellow and slightly softer. 14 karat is lighter in colour and stronger, which makes it ideal to wear every day. Both are real gold, never gold-plated.
Karat counts in 24 parts. 24 karat is (almost) pure gold: a beautiful deep colour, but so soft that a ring made of it quickly loses its shape. That's why goldsmiths mix gold with a little of other metals. It makes the gold stronger and sets the colour.
The higher the karat, the more gold. The hallmark says the same in thousandths: 585 means 585 of 1000 parts are gold.
| Karat | Hallmark | Gold | Colour | Strength | At TOV |
|---|---|---|---|---|---|
| 24k | 999 | 99.9% | Deep orange-yellow | Very soft | No |
| 18k | 750 | 75% | Deep, warm yellow | Softer | Yes |
| 14k | 585 | 58.5% | Warm, bright yellow | Strong | Yes, also white gold |
| 9k | 375 | 37.5% | Lighter, paler | Strong | No |
| 8k | 333 | 33.3% | Pale | Strong | No |
That little number is proof of what you're wearing: real gold, not plated. Every TOV piece is stamped 585 (14 karat) or 750 (18 karat), in a discreet spot such as the inside of a ring or near the clasp of a necklace. You also receive a personal digital certificate of authenticity with every piece.

More gold gives a richer, deeper colour. Side by side you see it straight away: 18 karat gold has a warm, almost honey-like glow. 14 karat is slightly lighter and fresher. Worn on its own, hardly anyone sees the difference.
14 karat. Because it contains more of the other metals, it's harder and less prone to scratches and dents. 18 karat is softer and shows small scratches sooner. Both last for years with a little care. Small scratches are part of a ring you really wear.
Stacking 14 and 18 karat? You'll see a slight colour difference. Some people love exactly that, others keep one karat per hand.
In Germany you see a lot of 333 gold, in the UK 375. It's cheaper, but it also contains much less gold: a third instead of half or more. That's why we don't make it. At TOV, you always wear at least 58.5% gold.
All our jewellery, including our gold piercings, is nickel-free and suitable for sensitive skin. Nickel is the best-known cause of itching and red patches with cheaper jewellery.

Yes. 14 karat gold is 58.5% pure gold, mixed with other metals for strength. It's not a thin layer of gold over another metal, as with plated jewellery.
585 means that 585 of 1000 parts are pure gold: 14 karat. On 18 karat, it says 750.
Real gold doesn't rust or oxidise. If a piece looks a little dull from soap, lotion or perfume, polish it with a soft cloth and it shines again.
Because it contains more gold: 75% instead of 58.5%. For the same design, you pay for more gold.
Absolutely. Side by side, you'll see a slight colour difference. Want it perfectly matched? Keep one karat per hand.
