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 $1,386 to $9,884, a $8,498 spread on the same certified stone. MOH London lists it at $9,884. 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.
