About This 1.51 Carat Cushion Lab Grown Diamond

This 1.51 carat cushion shape lab grown diamond is graded D color and SI1 clarity by IGI. Lab grown diamonds are chemically, optically, and physically identical to mined diamonds — graded to the same 4Cs standards at a fraction of the price.

  • Cushion shape: The cushion cut's softened square outline and large facets produce a distinctive warm glow.
  • D color: D color is the highest grade on the GIA color scale — completely colorless, with an icy white appearance even under magnification.
  • SI1 clarity: SI1 clarity means inclusions noticeable under 10x magnification but usually invisible to the naked eye, offering strong value.
  • IGI certified: Every lab grown diamond we sell includes an independent grading report. Learn more about diamond certificates and the 4Cs of diamond quality.
