About this 1.11ct lab-grown round diamond

This 1.11ct lab-grown round sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG772661002 or 772661002. Listed at 14 retailers as of November 1, 2026, with prices from £117 to £679, a £562 spread on the same certified stone. MOH London lists it at £679. 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.
