What do you see when you look at a diamond? You see light...reflected and refracted light. The more light you see reflected from a diamond’s facets, the more fire or brilliance the diamond displays. Brilliance is beauty, and no other diamond reflects more light than a HeartStar. The HeartStar diamond is one of the finest cut and proportioned round brilliant diamond produced in the world today. It reflects up to 93% of incoming light. Average diamonds don’t even come close.
