About this 5.28ct lab-grown cushion diamond

This 5.28ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836603655 or 836603655. Listed at 12 retailers as of October 26, 2026, with prices from $10,170 to $51,464, a $41,294 spread on the same certified stone. With Clarity lists it at $51,464. 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.
