About this 1.09ct lab-grown round diamond

This 1.09ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG795617961 or 795617961. Listed at 15 retailers as of November 4, 2026, with prices from €129 to €747, a €618 spread on the same certified stone. MOH London lists it at €747. 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.
