The crystals that are grown produce stones that, after polishing, generally weigh from ¾ carat to 1 ½ carat each. These cultured stones will generally look larger than natural colored stones of the same carat weight. Most natural colored diamonds are cut deeper to retain the color. The diamonds used in Solaura Jewelry have such vivid color, we are able to polish stones to the best proportions for fire and brilliance.
