  • Cut: One of the most important factors, cut gives a diamond its shape and determines how well light travels and reflects from it. Cut refers to the angles, facets, proportions, and finish of the diamond. In a 3 ct created diamond, high-quality cut is critical because customers pay a significant amount, and hence, expect a diamond that displays excellent performance, namely, fire, brilliance, and sparkle.

  • Clarity: Clarity determines the level of flawlessness in diamonds. The process of making diamonds in laboratories can, at times, lead to inclusions. Even though lab grown diamonds typically have a high clarity grade. Clarity has an impact on the diamond’s performance. A 3 ct lab grown diamond should have a high clarity grade, for example, Flawless (FL) or Internally Flawless (IF).
