About this 1.24ct lab-grown radiant diamond

This 1.24ct lab-grown radiant sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG635467768 or 635467768. Listed at 16 retailers as of October 30, 2026, with prices from $187 to $1,085, a $898 spread on the same certified stone. MOH London lists it at $1,085. 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.
