Round Cut Lab Grown Diamonds

Round cut lab diamonds are the most popular shape because their 57 to 58 facets are mathematically optimized for maximum brilliance, fire, and scintillation. Decades of cutting research have perfected the round brilliant's proportions, making it the benchmark for light performance. Its symmetrical shape also makes it versatile across virtually every ring setting style, from solitaire to halo to three-stone designs.

For a round lab grown diamond, prioritize an Excellent or Ideal cut grade above all other factors. Cut quality has the greatest impact on a round diamond's sparkle. Look for a table percentage between 54% and 60%, depth between 59% and 62.5%, and a crown angle near 34.5 degrees for the strongest light return. A well-cut round will outperform a diamond of higher color or clarity with inferior cut proportions.

Round cut lab made diamonds typically cost 20% to 40% more than fancy shapes like oval, cushion, or princess at the same carat weight and quality. This price difference exists because cutting a round brilliant wastes more of the rough crystal than other shapes. However, lab created rounds are still significantly more affordable than natural rounds, often 60% to 80% less at the same specifications.
