Lab-grown diamonds are beautiful and created in a laboratory rather than naturally occurring on the earth. Chemically, they are identical to their natural counterparts but at about 1/4 the price. We have a large range of certified lab-grown diamonds in every shape, carat weight, and quality to suit. We default to a high-quality D-E-F colour and VS2 clarity with triple Excellent cut for the best sparkle, but clients can select lower grades if they prefer.
Lab Diamonds are very popular and represent a pure diamond, ethically created and of excellent value. Contact our friendly team to discuss all your diamond requirements.
