About this 0.98ct lab-grown radiant diamond

This 0.98ct lab-grown radiant sits in the just-under-one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG592351626 or 592351626. Listed at 12 retailers as of October 26, 2026, with prices from £150 to £950, a £800 spread on the same certified stone. MOH London lists it at £950. 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.
