A one carat lab-grown diamond ring is the classic choice for an engagement or a milestone gift. Each solitaire here has a 1.00ct lab-grown diamond centre stone, with an independent IGI report to go with it. Choose solid 14ct or 18ct gold in white, yellow or rose, or sterling silver for a lower price, and we will make it to order in your size in around four weeks. Prefer a different style?
