About this 4.31ct lab-grown cushion diamond

This 4.31ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG564385689 or 564385689. Listed at 11 retailers as of November 1, 2026, with prices from $962 to $5,990, a $5,028 spread on the same certified stone. Brilliant Earth lists it at $5,990. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
