About this 1.01ct lab-grown round diamond

This 1.01ct lab-grown round sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG468103378 or 468103378. Listed at 17 retailers as of November 1, 2026, with prices from £101 to £1,046, a £944 spread on the same certified stone. MOH London lists it at £1,046. 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.
