Engagement rings UK (2026): the best under £1,000, £2,000 and £5,000

For most people, the best engagement ring is a classic diamond solitaire, and our pick is Mappin & Webb's Ena Harkness: half a carat in platinum, G colour and SI1 clarity, with a GIA certificate, according to Goldsmiths. Under £2,000, the Mappin & Webb Amelia; under £1,000, a 9ct white gold cluster.

Every ring here is sold new by Goldsmiths, a UK authorised retailer, at Goldsmiths' own price on the date shown. All are natural diamonds: we don't list lab-grown.

How we chose

We went through the engagement rings Goldsmiths has in stock, more than 300 of them, and compared Goldsmiths' details for each: the metal, the diamond's total weight, its colour and clarity grades, and whether it's GIA certified. Where a ring isn't certified, we say so. We earn a commission if you buy through our links, which never changes the price you pay.

What to look for

Grades and certificates are Goldsmiths' own.

• The setting. Goldsmiths groups its rings as solitaire (one diamond), halo (a ring of small diamonds around the centre), cluster (several stones together) and three stone.
• The grades. On GIA's scales, colour runs from D (colourless) to Z (light yellow, brown or grey), and clarity from Flawless to I3. G and H are near-colourless; SI1 means inclusions a skilled grader notices under 10x magnification, while I1 to I3 means inclusions that are obvious under 10x and may affect brilliance, according to GIA.
• Carat is weight: GIA defines a carat as 0.2 grams. "Total" (cttw) means all the diamonds in the ring added together, not the centre stone alone.
• The metal. Goldsmiths says platinum doesn't need re-plating like white gold, and 18ct gold is 75% pure gold. See gold and platinum explained.
