Although they were created in the 17th century, round cuts only became very popular in the last 100 years, and they have only continued to grow popular, becoming the most common diamond cut. No other cut provides more brilliance or sparkle than a round cut - it is also loved for its perfect circular shape. Because of the attention these cuts attract on their own, they are popularly set in the classic solitaire setting. This setting allows the most light to pass through to the gemstone, creating the perfect sparkle.
Approximately 75% of all diamonds that are sold are round cut. They are the perfect blend of elegance and simplicity. Because of their ability to reflect more light than any other shape, they conceal any color tints in diamonds exceptionally well through their sparkle. Round cut diamonds can also be set with side stones or in halo designs, which uniquely elevate the center stone. Although gold is the most popular metal for ring bands, a colorless round cut diamond would also pair very well with a white gold or platinum band for extra reflection, these metals are also preferable for those who are not a fan of the slight yellow tint that a gold band gives a diamond.
