About this 1.03ct lab-grown radiant diamond

This 1.03ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG752550250 or 752550250. Listed at 17 retailers as of October 30, 2026, with prices from £126 to £808, a £681 spread on the same certified stone. Flawless Fine Jewelry lists it at £808. 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.
