About this 1.04ct lab-grown round diamond

This 1.04ct lab-grown round sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG825674698 or 825674698. Listed at 9 retailers as of November 1, 2026, with prices from £119 to £692, a £573 spread on the same certified stone. MOH London lists it at £692. 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.
