Lab Grown Diamond Engagement Rings, Handmade in Sussex
At Pruden & Smith, every lab grown diamond engagement ring is designed and handmade by our goldsmiths at our workshop in Ditchling, Sussex. A lab grown diamond is a real diamond — grown with advanced technology that mirrors the natural process to produce a stone identical in chemistry, sparkle and hardness to a mined one, yet fully traceable and conflict-free. Because lab grown diamonds cost less than equivalent mined stones, they let you choose a larger or higher-grade diamond without stretching your budget, with prices starting from £1,320.
Choose from elegant solitaires, hidden halos, art deco and trilogy designs, or our signature Water Bubbles, Spiky and Vintage styles — then personalise the diamond shape, metal and setting to make it your own. Prefer something entirely unique? Our team can design a bespoke lab grown engagement ring with you, from first sketch to finished ring. Every as-seen engagement ring is backed by our lifetime guarantee, so it is made to be worn for a lifetime.
Frequently Asked Questions
Are lab grown diamonds real diamonds?
Yes. A lab grown diamond is a real diamond — it has exactly the same chemical, physical and optical properties as a mined diamond. The only difference is origin: it is grown in a laboratory that recreates the intense heat and pressure found deep in the earth, rather than being mined. To the eye, and under a jeweller's loupe, the two are identical.
Are lab grown diamonds cheaper than natural diamonds?
Generally, yes. A lab grown diamond usually costs less than a mined diamond of the same size, colour and clarity. That means you can often choose a larger or higher-grade stone for the same budget, or the same look for less. Our lab grown diamond engagement rings start from £1,320.
Are lab grown diamond engagement rings ethical?
Lab grown diamonds are conflict-free and fully traceable, because they are created in a controlled laboratory rather than mined. For couples who want the beauty of a diamond with complete peace of mind over its origin, they are an increasingly popular choice. We are always happy to talk you through both lab grown and natural options.
Where are your lab grown engagement rings made?
Every ring is designed and handmade by our own goldsmiths at our workshop in Ditchling, Sussex. You are welcome to visit us to see the workshop and try on designs, and we ship handmade rings across the UK.
Can I choose the diamond shape, metal and setting?
Yes. Most designs can be made with your choice of diamond cut — round, oval, emerald, pear, cushion, princess or marquise — and in your preferred metal and setting. If you would like something completely original, we can design a bespoke lab grown diamond engagement ring with you, from first sketch to finished ring.
Do you offer ring sizing and resizing?
Yes. We will help you find the right size before you order, and our ready-to-ship rings can be resized to fit. Every as-seen engagement ring is also covered by our lifetime guarantee, so it is cared for long after the proposal.
