About this 2.04ct lab-grown round diamond

This 2.04ct lab-grown round sits in the two to three carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG478110986 or 478110986. Listed at 12 retailers as of November 5, 2026, with prices from £758 to £5,020, a £4,262 spread on the same certified stone. MOH London lists it at £5,020. 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.
