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 LG677562303 or 677562303. Listed at 16 retailers as of October 30, 2026, with prices from £106 to £682, a £576 spread on the same certified stone. Flawless Fine Jewelry lists it at £682. 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.
