About this 1.22ct lab-grown radiant diamond

This 1.22ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG625480575 or 625480575. Listed at 9 retailers as of October 29, 2026, with prices from $610 to $2,045, a $1,435 spread on the same certified stone. MOH London lists it at $2,045. 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.
