This 1ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816610744 or 816610744. Listed at 8 retailers as of October 26, 2026, with prices from $444 to $1,035, a $591 spread on the same certified stone. MOH London lists it at $1,035. 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.
