The round diamond is the most popular and traditional diamond shape. The round cut optimizes the properties of the diamond rough to create the maximum potential light refraction.
A round brilliant stone will have 58 facets and is better at hiding imperfections in color and clarity than fancy cut diamonds. Round stones cost the most per carat because the manufacturing of these stones requires more diamond rough and because demand for round diamonds is very high.
The CUT of a round diamond will have the greatest impact on the brilliance of the stone. HYSTR recommends that customers choose round diamonds with Ideal, Excellent or Very Good cuts. Because round diamonds are better at hiding color and clarity imperfections, buyers can often find the best value stone by choosing a round diamond that is SI clarity and H-I color.
