About this 0.65ct lab-grown round diamond

This 0.65ct lab-grown round sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LGS3B38479 or S3B38479. Listed at 2 retailers as of October 30, 2026, with prices from $654 to $1,180, a $526 spread on the same certified stone. Yorxs 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.
