About this 2.31ct lab-grown cushion diamond

This 2.31ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG490174620 or 490174620. Listed at 5 retailers, with prices from $1,030 to $2,406 at Rare Carat, a $1,376 spread on the same certified stone. 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.
