About this 1.23ct lab-grown radiant diamond

This 1.23ct lab-grown radiant sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG536293293 or 536293293. Listed at 19 retailers as of October 30, 2026, with prices from £139 to £857, a £718 spread on the same certified stone. Reve Diamonds lists it at £857. 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.
