About this 5.03ct lab-grown cushion diamond

This 5.03ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG821639484 or 821639484. Listed at 12 retailers as of October 26, 2026, with prices from $14,963 to $57,993, a $43,030 spread on the same certified stone. With Clarity lists it at $57,993. 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.
