About this 1.01ct lab-grown radiant diamond

This 1.01ct 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 LG375940239 or 375940239. Listed at 8 retailers as of November 6, 2026, with prices from $873 to $3,369, a $2,496 spread on the same certified stone. NZ Jewellers lists it at $3,369. 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.
