About this 1.23ct lab-grown radiant diamond

This 1.23ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG617447194 or 617447194. Listed at 11 retailers as of November 2, 2026, with prices from £124 to £1,200, a £1,076 spread on the same certified stone. Do Amore Diamonds lists it at £1,200. 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.
