Round Brilliant Cut Diamonds The most popular diamond shape and generally the brightest when cut to highest specifications. The modern Round Brilliant Cut Diamond was invented by Marcel Tolkowsky in 1919 and it's the most popular shape of diamond because it's fiery, practical, will suit almost every finger, and of course because it's round (the most superior shape.) The price of a round diamond is usually the highest (excluding modern patented cuts), when purchased individually (not as a pair), mainly because it is consistently popular throughout the year, unlike fancy shape diamonds which can sometimes be seasonal or drop out of fashion for a few months or years before returning back again. The round brilliant cut usually contain 57 - 58 facets with a total depth that's around 60% from the diameter for a properly proportioned diamond, however this is a textbook guide and not a rule as the total depth can also fluctuate slightly without affecting the diamond's beauty.
