About this 1.05ct lab-grown radiant diamond

This 1.05ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG794611504 or 794611504. Listed at 11 retailers as of October 28, 2026, with prices from $426 to $2,200, a $1,774 spread on the same certified stone. Brilliant Earth lists it at $2,200. 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.
