About this 1.01ct lab-grown radiant diamond

This 1.01ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG670440000 or 670440000. Listed at 23 retailers as of October 30, 2026, with prices from $330 to $1,851, a $1,520 spread on the same certified stone. Brilliant Earth lists it at $1,851. 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.
