About this 0.9ct lab-grown radiant diamond

This 0.9ct lab-grown radiant sits in the just-under-one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG836677679 or 836677679. Listed at 10 retailers as of November 1, 2026, with prices from £281 to £775, a £494 spread on the same certified stone. Brilliant Earth lists it at £775. 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.
