This 1.21ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG825627372 or 825627372. Listed at 12 retailers as of October 25, 2026, with prices from $211 to $1,096, a $885 spread on the same certified stone. MOH London lists it at $1,096. 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.
