About this 3.08ct lab-grown cushion diamond

This 3.08ct 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 LG821639540 or 821639540. Listed at 11 retailers as of October 28, 2026, with prices from $2,842 to $9,406, a $6,564 spread on the same certified stone. With Clarity lists it at $9,406. 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.
