1 Carat Engagement Rings

A 1 carat diamond offers the perfect mix of size, sparkle and value, which is why it is the most requested weight in the UK. At Engagement Ring Boutique in Hatton Garden we hand-pick every GIA-certified diamond, then set it in designs that let the stone shine.

Our collection spans all popular shapes: round, oval, princess and cushion. Choose a classic four-claw solitaire for timeless elegance, a shimmering halo for extra sparkle or a trilogy that celebrates past, present and future. Each ring is crafted in 18 ct white, yellow or rose gold, or in enduring platinum.

Because every relationship is unique we also offer a bespoke design service. Our GIA-trained gemmologist will meet you in our Greville Street showroom, explain the Four Cs in plain words and present diamonds that match your budget. Once you have chosen, our master goldsmiths create your ring within four weeks.

Prices for a natural 1 carat diamond ring start at around £4,000, while lab-grown 1 carat diamond rings begin from about £1,500. Every purchase includes free insured UK delivery, one complimentary resize within the first year and a lifetime manufacturing warranty.
