Pre-Set Engagement Rings
Complete engagement rings, ready to order: our settings with lab-grown side stones and a hand-picked lab-grown diamond of 1, 2 or 3 carats (colour D to F, clarity VVS2 or better), at one price.
Prefer to choose every detail? Design your own ring.
Order by 2 December for priority production. Every order placed by 2 December 2026 goes into production straight away, with priority. We aim to dispatch before our workshop closes on 21 December, but some designs take longer, and courier times and public holidays add to delivery, so we can’t promise delivery before Christmas. Your delivery period and date are shown before you order. Need your piece by a set date? Tell us before you order.
