Every ring is designed around the diamond you choose — natural or lab-grown, certified either way. We'll tell you when the cheaper stone is the better stone.

Choose the exact diamond for your ring
On every lab-grown ring, Simon’s published standard — D to G colour, VS2 to VVS1 clarity, excellent cut and polish, IGI certified — selects five diamonds from those available today, from the most affordable to the finest. Turn each one in 360°, choose yours, and reserve it online. Simon confirms your stone and its certificate personally before it is set.
