Lab Grown Diamond Rings

Lab-grown diamonds are real diamonds — same carbon, same hardness, same sparkle — grown in a lab instead of mined, which is why a certified 1ct lab-grown engagement ring here starts around R9,000 and a half-carat from R7,999. Cassims & Co. keeps 60+ lab-grown diamond rings in stock in Johannesburg, each with an IGI or equivalent certificate.

Shop by cut and style: 1ct oval solitaires (our best seller), round and emerald cut, halo and hidden-halo settings, lab-grown wedding bands and eternity rings, in 9ct and 18ct white, yellow and rose gold.

Read our lab-grown vs natural vs moissanite guide, or let the design studio make your setting to order. Rings are resized in-house before dispatch. Visit Mall of the South or Greenstone or order online with nationwide delivery.
