About this 1.02ct lab-grown cushion diamond

This 1.02ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836619623 or 836619623. Listed at 16 retailers as of October 31, 2026, with prices from $668 to $3,246, a $2,578 spread on the same certified stone. Brilliant Earth lists it at $3,246. 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.
