About this 5.31ct lab-grown cushion diamond

This 5.31ct 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 LG823695226 or 823695226. Listed at 17 retailers as of October 29, 2026, with prices from $8,583 to $31,187, a $22,604 spread on the same certified stone. Michael Trio lists it at $31,187. 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.
