This 2.09ct 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 LG407941775 or 407941775. Listed at 11 retailers as of November 5, 2026, with prices from £721 to £5,141, a £4,420 spread on the same certified stone. MOH London lists it at £5,141. 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.
