About this 1.21ct lab-grown asscher diamond

This 1.21ct lab-grown asscher 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 LG831684504 or 831684504. Listed at 12 retailers as of November 3, 2026, with prices from $627 to $4,576, a $3,949 spread on the same certified stone. Brilliant Earth lists it at $4,576. 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.
