About this 4.31ct lab-grown cushion diamond

This 4.31ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG802605881 or 802605881. Listed at 21 retailers as of November 1, 2026, with prices from $1,066 to $6,378, a $5,312 spread on the same certified stone. Brilliant Earth lists it at $6,378. 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.
