Scientifically speaking, the round brilliant cut diamond, designed with 57-58 facets, has the most sparkle. Of course, because each diamond is unique, it is still important to take a look at the individual diamond to evaluate its sparkle.
Round brilliant cut diamonds look larger than other cuts, largely because much of the diamond’s surface area is captured in the circular shape. Elongated cuts, including oval, emerald, and marquise cut diamonds also make for a larger looking diamond.
Diamond color is actually a reference to a diamond’s lack of color, and the less color a diamond has, the higher its color grade. Colorless diamonds are graded D, E, or F. Near-colorless diamonds are graded G-J.
Diamonds need to be cut into a faceted shaped stones from their rough natural state. First, the selected area must be separated from the rough diamond, either by cleaving, or by using a diamond saw or laser. Next, two diamonds are set onto opposite-spinning axles to grind the diamond into its shape in a process known as bruiting or girdling. Finally, the stone is polished to brilliant perfection.
