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 LG836617854 or 836617854. Listed at 14 retailers as of November 4, 2026, with prices from $674 to $2,767, a $2,093 spread on the same certified stone. Brilliant Earth lists it at $2,767. 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.
