About this 1.15ct lab-grown radiant diamond

This 1.15ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG851653618 or 851653618. Listed at 13 retailers as of November 4, 2026, with prices from $226 to $974, a $748 spread on the same certified stone. Rare Carat lists it at $974. 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.
