About this 1.02ct lab-grown round diamond

This 1.02ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LGS3G98631 or S3G98631. Listed at 2 retailers as of October 30, 2026, with prices from $1,686 to $2,850, a $1,163 spread on the same certified stone. Yorxs lists it at $2,850. 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.
