About this 3.1ct lab-grown cushion diamond

This 3.1ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG780663587 or 780663587. Listed at 13 retailers as of October 29, 2026, with prices from $3,164 to $13,044, a $9,880 spread on the same certified stone. Brilliant Earth lists it at $13,044. 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.
