The Round Cut Diamond is the most ideal and well-knowing shape from the beginning.  We are in 2019 right now and exactly 100 years ago in 2019 with the publication of Marcel Tolkowsky’s thesis “Diamond Design,” the round shape diamond first comes into prominence. It is more seen and loved by the color white Because of Its 57 to 58 facets bring out the most brilliance, fire, and sparkle of all the shapes. While in fancy colored diamond round is not used offend This is because the round cut does not maximize the depth and richness of color in fancy color diamonds. Round cut diamonds would be suitable and best set in prongs, tension setting, and bezel setting since they increase the expression of the diamond and brings out its brilliance. Additionally, an ample variety of similar sized small round diamonds set in pave setting or flush setting makes an aesthetically crafted diamond ring for an anniversary or an engagement ring.
