The Science of Sparkle - Factors that determines the value of a diamond engagement ring
The value of a diamond is determined by its Carat Weight, Clarity, Cut, and Color. All of these factors play a critical role in determining the diamond's value. No single characteristic outweighs another. A diamond is less expensive when there is a yellow hue. An intense pink or blue hue commands a higher value.
