About this 1.31ct lab-grown radiant diamond

This 1.31ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG524226041 or 524226041. Listed at 6 retailers as of November 2, 2026, with prices from £147 to £1,764, a £1,617 spread on the same certified stone. Michael Trio lists it at £1,764. 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.
