About this 1.55ct lab-grown cushion diamond

This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG547257106 or 547257106. Listed at 16 retailers as of November 4, 2026, with prices from $422 to $3,583, a $3,161 spread on the same certified stone. Brilliant Earth lists it at $3,583. 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.
