About this 1ct lab-grown round diamond

This 1ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG782622002 or 782622002. Listed at 10 retailers as of October 25, 2026, with prices from €309 to €970, a €661 spread on the same certified stone. MOH London lists it at €970. 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.
