Your Perfect Round diamond engagement rings

The traditional choice for all occasions and preferred by many for their personal investment portfolio. The depth percentage of a round diamond should range between 58 to 63 percent and the table percentage should range between 55 to 64 percent.

Round diamond is the best seller of all diamond shapes. The vast majority of sold diamonds are rounds. The round shape makes it easy to mathematically calculate the reflected light rays from it thus decide if a certain set of parameters of a certain diamond will yield the maximum reflected rays –the maximum brilliance That we call Ideal-Cut. There is no one superior cut that all others are inferior to it, there may be numerous combinations that yields an Ideal-Cut diamond. Even though they are called "Round", they are never 100% round but have a minimum and maximum diameter size as they are rounded by hand or machines rubbing diamond to diamond. A difference of up to 1.5% is acceptable.
