About this 0.73ct lab-grown cushion diamond

This 0.73ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG777618047 or 777618047. Listed at 6 retailers as of October 29, 2026, with prices from $384 to $1,068, a $683 spread on the same certified stone. Brilliant Earth lists it at $1,068. 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.
