About this 4.02ct lab-grown cushion diamond

This 4.02ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG787620842 or 787620842. Listed at 14 retailers as of October 30, 2026, with prices from $4,392 to $24,380, a $19,988 spread on the same certified stone. With Clarity lists it at $24,380. 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.
