About this 1.03ct lab-grown radiant diamond

This 1.03ct 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 LG597398717 or 597398717. Listed at 24 retailers as of October 30, 2026, with prices from $148 to $960, a $812 spread on the same certified stone. Flawless Fine Jewelry lists it at $960. 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.
