The exceptional round brilliant diamond has been engineered to achieve optimum light return. When each of its 58 facets are cut with perfect precision, this abundance of light creates a balance of fire, brilliance and scintillation. All of this translates to a striking, sparkly diamond.
Marcel Tolkowsky, a mathematician and engineer, is widely credited with creating the ‘ideal cut’ proportions for a round brilliant diamond. His original design provided the foundations of a round cut diamond, which has since been improved to further light return and better suit modern diamond cutting techniques.
Instead of delving deep into proportions and percentages, modern buyers can benefit from GIA diamond reports. Expert gemmologists scrutinize the diamonds in a complex series of tests, before issuing them consumer-friendly cut grades.
The specific proportions of the diamond can be found on the report, along with the given grade; Excellent, Very Good, Good, Fair and Poor. The report will also outline the other characteristics of your round diamond; clarity, color and carat weight.
All of our GIA round diamonds can be set in a piece of jewelry of your choosing.
