About this 3.01ct lab-grown cushion diamond

This 3.01ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG840657033 or 840657033. Listed at 11 retailers as of November 6, 2026, with prices from $483 to $3,294, a $2,811 spread on the same certified stone. Brilliant Earth lists it at $3,294. 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.
