Ritani has a large selection of lab grown diamonds in the 2 carat range in a variety of shapes. Round cut lab grown diamonds are the most popular lab grown diamond shape, followed by the princess cut and the cushion cut. If you are looking for a 2 carat lab grown diamond that appears larger, choose a marquise cut, pear cut, or oval cut lab grown diamond. These trending lab grown diamond shapes appear bigger than they really are because of their large surface area. A halo setting can also enhance your 2 carat lab grown diamond ring by making it appear larger.
