Collection: 1 Carat Heart Lab Grown Diamonds

Browse loose 1 carat heart lab grown diamonds (1.00–1.99 ct), sorted from the lowest price. Heart shapes are a romantic brilliant cut; a well-cut heart shows a clear, even outline.

• Real lab grown diamonds from DovEggs partner labs (our Group lab diamonds), with price match.
• Certificates: most of these stones come with an IGI report; the report number is laser-inscribed on the girdle and can be verified online.
• Timing: each stone reaches our workshop in about 2 or about 7 business days depending on the supplier — every stone's page shows its timing.
• Make it a ring: any stone here can be set in a made-to-order DovEggs setting — start with a loose lab grown diamond.
