About this 2.31ct lab-grown cushion diamond

This 2.31ct lab-grown cushion sits in the two to three carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG539225365 or 539225365. Listed at 15 retailers as of October 31, 2026, with prices from $462 to $1,920, a $1,458 spread on the same certified stone. Brilliance lists it at $1,920. 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.
