Jewellery Buying Guide
Choosing fine jewellery is easier when you know what to look for. This guide explains diamond quality, gold karats, ring sizes and everyday care in plain language.
Diamonds: the 4Cs
- Cut — how well a diamond is shaped and polished. A good cut returns more light, which is what makes a diamond sparkle.
- Colour — graded from D (colourless) to Z (light yellow). Near-colourless stones look bright white in white gold; warmer stones can look lovely in yellow gold.
- Clarity — how free a stone is from tiny natural marks, from FL (flawless) to I (included). Many marks cannot be seen without magnification.
- Carat — the weight of a diamond (1 carat = 0.2 g). Our product pages show the total diamond weight of each piece in carats (ct).
If a diamond comes with an independent grading report, the report number can be checked on the laboratory’s own website. Ask our team about the details of any piece.
Gold karats
Karat (K) tells you how much pure gold is in the metal. The rest is a mix of other metals that adds strength and colour.
Pure gold. Very soft, so it is mostly used for bullion and coins.
Rich colour and soft; popular for traditional plain-gold jewellery.
Strong enough to hold diamonds and gemstones securely. Our collection is made in 18K gold.
Harder and more affordable, with a paler colour.
Yellow, white and rose gold are all real gold. The colour comes from the other metals in the alloy: copper gives rose gold its warmth, while white gold is alloyed with white metals and often finished with a bright plating.
Finding your ring size
Measure the inside diameter of a ring that fits you well and compare it with this chart. Measure at the end of the day, when fingers are slightly larger, and go up half a size for wide bands.
| Inside diameter | US size | EU size |
|---|---|---|
| 15.7 mm | 5 | 49 |
| 16.5 mm | 6 | 52 |
| 17.3 mm | 7 | 54 |
| 18.1 mm | 8 | 57 |
| 18.9 mm | 9 | 59 |
| 19.8 mm | 10 | 62 |

Caring for your jewellery
- Put jewellery on after perfume, lotion and hairspray, and take it off for swimming, the gym and housework.
- Clean gently with warm water, a drop of mild soap and a soft brush, then dry with a soft cloth.
- Store pieces separately so diamonds do not scratch other jewellery.
- Have settings checked from time to time, especially on rings you wear every day.
