Materials
Is the gold solid or plated?
Solid. Every piece is made in solid 10K, 14K or 18K gold. We do not sell plated, gold-filled or vermeil jewelry.
What is the difference between 10K, 14K and 18K?
The karat number is how much pure gold is in the alloy. 18K is richest in color and softest; 10K is the most hard-wearing and the most affordable; 14K sits between the two and is what most people choose for a ring worn every day.
Are lab grown diamonds real diamonds?
Yes. Chemically and optically identical to mined diamonds — same material, same hardness. The difference is origin and cost per carat, not substance. Ours are IGI certified.
What is moissanite?
A different stone from diamond, not an imitation of one. It is very hard, highly brilliant, and considerably less expensive per carat. Ours is GRA certified.
Are your natural diamonds certified?
Yes. Natural diamonds are GIA certified, lab grown diamonds are IGI certified, and moissanite is GRA certified. The certificate travels with the piece.
Ordering
How long until it arrives?
About 4 business days to make and dispatch, plus about 4 business days in transit. See Shipping & Delivery.
Will it arrive before Christmas?
If you order by Monday 14 December 2026, yes. That is about 4 business days to make and dispatch plus about 4 business days in transit, which brings it to you by Christmas Eve. Order after 14 December and the piece is still made and sent, but is likely to arrive after Christmas. If you are close to the date and worried, email us before ordering.
Do you charge for shipping?
No. Free worldwide delivery by DHL on every order, and taxes are included in the price you see.
Will I pay customs duty?
Possibly, depending on your country. Duties are set by the destination and collected by the carrier. Email us if you want to know what to expect.
Fit and returns
What if the ring does not fit?
We resize it. See Ring Sizing.
What is your returns policy?
60 days, free. See Returns & Exchanges.
Can everything be resized?
Most rings, yes. Full eternity bands, where stones run the whole way round, generally cannot be resized without being remade. We will tell you which case applies to your piece.
