About this 1ct lab-grown cushion diamond

This 1ct 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 LG825655920 or 825655920. Listed at 14 retailers as of October 30, 2026, with prices from $562 to $3,269, a $2,707 spread on the same certified stone. Brilliant Earth lists it at $3,269. 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.
