About this 0.9ct lab-grown radiant diamond

This 0.9ct lab-grown radiant sits in the just-under-one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG442048690 or 442048690. Listed at 13 retailers as of October 26, 2026, with prices from £143 to £827, a £685 spread on the same certified stone. MOH London lists it at £827. 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.
