The objective when cutting a diamond into a particular shape is to allow as much light that enters the crown or "top" of the diamond to bounce around the diamond before exiting back out of the crown. This is what gives the diamond it's timeless sparkle. Over the years diamonds have evolved to take on new shapes that allows more light to be captured. Today the most popular cut is the Modern Brilliant Round.
