Brilliance, also called sparkle, is the striking feature in diamonds that sets them apart from other gemstones. Although all diamonds sparkle, some are more brilliant. So what causes diamonds to sparkle?
Understanding Diamond Sparkle
Before we find out the diamond cut that sparkles most, let's understand what causes diamonds to sparkle. The ability of a diamond to sparkle depends on how it takes in light and reflects it to your eye. A diamond that reflects more light from its facets will sparkle more. In this respect, a diamond's sparkle mainly depends on the cut. Typically, diamond cuts with more facets sparkle the most. These facets act as mirrors, reflecting the light inside the diamond and bouncing it back out of the diamond to create magnificent sparkle.
The Round Brilliant Cut Diamonds Sparkles the Most
Brilliant cut diamonds were deliberately engineered to have the most facets and sparkle. The round brilliant cut diamonds have 57 or 58 facets and sparkle the most. According to Gemological Institute of America (GIA), due to their classic round shape and a maximum number of facets, these diamonds grab and reflect light better than any other diamonds.
When you examine a round brilliant cut diamond under a microscope, you'll realize that each facet has an octagon shape, and the sides measure 11 to 12 angles.
Marcel Tolkowsky is credited for engineering the round brilliant cut diamond for his Ph.D. thesis in 1919. He created a new formula that created the most brilliant diamond—the round brilliant cut diamond.
