A lab grown diamond is a real diamond, with the same carbon, the same hardness and the same sparkle as a natural one. It is grown in a laboratory instead of forming deep underground, and it costs a fraction of the price of a natural diamond of the same size and grade, so your budget goes much further. Every design below can be set with a certified lab grown diamond you choose yourself from our live stock, and is made to order in platinum, 18ct or 9ct gold in our Cotswolds workshop.

What Is a Lab Grown Diamond?
Lab grown diamonds are made either by recreating the heat and pressure that form diamonds in the earth (HPHT), or by building the crystal up layer by layer from a carbon-rich gas (CVD). The result is chemically, physically and optically a diamond. You can't tell one from a natural diamond by eye, or with a jeweler's loupe; only specialist laboratory equipment can. Every lab grown diamond we offer for a ring comes with its own photo and a grading report that states it is laboratory grown.
Lab Grown or Natural?
The difference is origin and price, not looks. A natural diamond formed over millions of years and is rare, which is why it costs more. A lab grown diamond gives you the same look for much less, so the budget for a natural diamond will often buy a lab grown one twice the size or more. Both are graded on the same 4Cs, so you can compare them side by side in our lab grown diamond search and our full diamond search. The setting, the metal and the workmanship are exactly the same either way.
Choosing Your Lab Grown Diamond
Cut matters most for sparkle: choose Excellent or Ideal where the report gives a cut grade. Color: D to F looks icy white, and G to H still looks white in platinum or white gold; in yellow or rose gold you can go a little lower without seeing it. Clarity: VS1 or VS2 is clean to the eye in almost every stone, so you rarely need to pay for VVS. Carat: with lab grown, many couples choose a larger stone than they first planned. See every shape in our guide to engagement rings by diamond shape.
