2 Carat Lab Grown Diamonds

The 2 carat lab grown diamond is a precisely engineered gemstone gemstone that weighs 0.4 grams and replicates the physical, chemical and optical characteristics of a natural diamond. It is made by advanced CVD or HPHT techniques, guaranteeing purity, structure and excellent brilliance. A 2 carat synthetic diamond provides the same luxury look at a much lower price. These stones are graded by IGI for cut, clarity, color, and carat. At Flawless Fine Jewellery Hatton Garden, London, we offer ethically sourced, high-clarity options ideal for premium jewellery and modern engagement ring designs.

How big is a 2 carat lab grown diamond: carat weight vs diamond size

The 2 carat diamond size usually has a diameter of about 8.1 mm for a well-cut round shape. But this size perception may change according to shape and cut quality. Although carat is a measure of weight (0.4 grams), the real visual size varies with depth, table and proportions. A shallow cut may appear larger but reduce brilliance. A 2 carat man made diamond is identical in dimensions and density with a natural one. Choosing the right cut ensures optimal balance between spread and sparkle, making size and light performance equally important in diamond selection.
