About this 1.29ct lab-grown radiant diamond

This 1.29ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG849651011 or 849651011. Listed at 12 retailers as of November 3, 2026, with prices from £153 to £933, a £781 spread on the same certified stone. Brilliant Earth lists it at £933. 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.
