About this 2.31ct lab-grown round diamond

This 2.31ct lab-grown round sits in the two to three carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG451057413 or 451057413. Listed at 9 retailers as of October 29, 2026, with prices from $1,774 to $10,660, a $8,886 spread on the same certified stone. MOH London lists it at $10,660. 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.
