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 $12,005 to $46,530, a $34,525 spread on the same certified stone. With Clarity lists it at $46,530. 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.
