About this 1.21ct lab-grown oval diamond

This 1.21ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG739579955 or 739579955. Listed at 24 retailers as of November 1, 2026, with prices from $261 to $2,120, a $1,859 spread on the same certified stone. Brilliant Earth lists it at $2,120. 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.
