Loose Round Cut Diamonds

The modern round cut is the culmination of centuries' work. It was developed by Marcel Tolkowsky in 1919, but its ancestry can be traced back to the Old European Cut, an invention of the 19th century. A round diamond is cut to achieve maximum brilliance, fire and sparkle. Excel Diamonds offers a wide selection of round cut stones graded by fine laboratories such as GIA, AGS, and HRD. Please contact us if you would like us to work up of any of these beautiful stones.
