The Guides

Jewellery Buying Guides

Fine jewellery is worth understanding before you buy it. These are our honest guides to choosing well, written the way we would explain it to you in the atelier.

Buying a piece you intend to keep is a different decision from buying something for the season. It rewards a little knowledge: what the metal really is, why one stone suits a month, how a name necklace is made so it lasts. These guides exist to give you that, plainly and without the sales gloss.

Choose the guide that fits what you are looking for. Each one is written to help you decide with confidence, then find the piece that is right.

How to use these guides

If you are buying a gift, start with the person. A name or an initial makes a personalised piece; a birth month points you to a birthstone. If you are buying for yourself and care most about how a piece will wear over the years, read the fine jewellery guide first, because the metal decides that more than anything else.

Every piece we make is solid gold and made to order in our London atelier, so it is built to be kept. The guides are here to help you choose the right one the first time.

Common questions

What is my birthstone?

Your birthstone is set by your birth month, from January garnet through to December turquoise. The full UK list, with each stone's colour and meaning, is in our Birthstones by Month guide.

What is the difference between solid gold and gold-plated?

Solid gold is gold all the way through, so it does not wear off or tarnish. Gold-plated is a thin layer of gold over a base metal, which fades with wear. We explain what that means for a piece you wear daily in our solid gold vs gold-plated guide.

Which gold should I choose, 9ct or 18ct?

It depends on the balance you want between durability, colour and price. 9ct is the hardest and most affordable, and 18ct is the richest in colour and purity. Our gold guide walks through how to decide.
