About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant 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 LG816615712 or 816615712. Listed at 17 retailers as of October 28, 2026, with prices from $256 to $2,110, a $1,854 spread on the same certified stone. Rare Carat lists it at $2,110. 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.
