This 1.01ct lab-grown round sits in the classic one-carat band, graded E colour (colourless) and I1 clarity (included), with a very-good cut grade and certified by IGI LG12450912 or 12450912. Listed at 2 retailers as of October 29, 2026, with prices from £230 to £1,024, a £794 spread on the same certified stone. MOH London lists it at £1,024. 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.
