Round Diamonds are called brilliant which is a form of cut which is a cone shaped. It’s designed to maximise the light reflected to show a sparkle or fire.
A round loose diamond has 58 facets or 57 if the culet is excluded.
Since the introduction of laser cutting technologies and robotic processes the diamond cutting industry has worked towards the idea cut.
There are many certifications which observe the cut of the 58 facets of a diamond and grade accordingly the diamond centre focus on only GIA and IGI diamond certifications.
A diamond exhibits exceptional brilliance when it has multiple facets when cut into shape. Although a diamond loses its weight considerably after cutting, the round shaped diamonds are exquisite in its appeal and of exceptional value. Round diamonds are generally obtained from those uncut diamonds which have eight triangular faces and by applying the latest cutting techniques, two round diamonds may be cut from one piece of raw diamond.
Round diamonds are the most expensive and popular among all diamonds and that is why they find their places in engagement rings, pendants and earrings. A round brilliant cut diamond has 58 facets which makes these unique pieces of diamond forever to be an indispensable part of your life.

Those having the pavilion ending at a point at the bottom, the culet are absent.
Techniques of cutting the round diamonds adopted in early stages were based on the study of reflection and refraction of light in diamonds which provided the diamonds to exhibit the brilliance of return and dispersion of light, making them unique pieces of gems. This type of cut is known as the Tolkowsky cut which differs from the modern techniques of cutting the round diamonds. Modern techniques of cutting have no culet and the range of the table size is bigger. This technique involves cutting the facets of the lower girdle are cut deeper as compared to the traditional cut. The cut goes down to the pavilion as compared to the old methods where the cut was usually up to about 1/3rd of the pavilion.
Cutting the round diamonds into their perfect shape is termed as the “ideal cut” which is the modern process to discover the brilliance of the round diamonds which is maximum in size and fire. Optimizing the cut of round diamonds to ideal proportions, a modern cutter often disillusioned to make the ideal cut as well as to ensure that the diamond has the maximum weight. It may take a long time than usual to cut the round diamonds to such proportions which are considered to be ideally proportional with symmetrical ratings and an ideal finish as compared to the usual parameters of cutting.
Cutting the diamond into a round shape while maintain the usual weight is very difficult as compared to the cutting of raw diamonds. This makes the brilliant round diamonds cut the most expensive of all. Smaller table cuts are the most expensive and the better cuts because the size of the round diamonds are measured by the diameter measured in millimeters and according to the table size. Round diamonds are the most expensive diamonds due to their versatility in being used in a variety of jewelry and in exquisite styles. The ultimate beauty in round diamonds is the extraordinary sparkle which makes it the most sought after diamond in the world.
