About this 1.09ct lab-grown radiant diamond

This 1.09ct lab-grown radiant sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG311250121 or 311250121. Listed at 4 retailers as of November 4, 2026, with prices from $269 to $1,180, a $911 spread on the same certified stone. NZ Jewellers lists it at $1,180. 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.
