About this 3.51ct lab-grown cushion diamond

This 3.51ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG726509052 or 726509052. Listed at 17 retailers as of October 27, 2026, with prices from $921 to $4,070, a $3,149 spread on the same certified stone. Rare Carat lists it at $4,070. 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.
