About this 1.31ct lab-grown oval diamond

This 1.31ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG729571580 or 729571580. Listed at 16 retailers, with prices from $270 to $2,286 at Queensmith, a $2,016 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.
