About this 2.31ct lab-grown cushion diamond

This 2.31ct lab-grown cushion sits in the two to three carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG542207742 or 542207742. Listed at 6 retailers as of October 29, 2026, with prices from £426 to £1,041, a £615 spread on the same certified stone. MOH London lists it at £1,041. 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.
