About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG496107452 or 496107452. Listed at 5 retailers as of October 31, 2026, with prices from £296 to £659, a £363 spread on the same certified stone. Diamond Quarter lists it at £659. 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.
