About this 1.07ct lab-grown radiant diamond

This 1.07ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG592351677 or 592351677. Listed at 13 retailers as of October 27, 2026, with prices from £227 to £621, a £394 spread on the same certified stone. MOH London lists it at £621. 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.
