About this 1.03ct lab-grown cushion diamond

This 1.03ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840634759 or 840634759. Listed at 13 retailers as of October 25, 2026, with prices from $460 to $2,680, a $2,220 spread on the same certified stone. Brilliant Earth lists it at $2,680. 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.
