About this 1.39ct lab-grown radiant diamond

This 1.39ct 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 LG612346251 or 612346251. Listed at 5 retailers as of October 28, 2026, with prices from £277 to £1,008, a £731 spread on the same certified stone. Jared lists it at £1,008. 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.
