About this 1.15ct lab-grown cushion diamond

This 1.15ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG574346095 or 574346095. Listed at 11 retailers as of November 2, 2026, with prices from £236 to £834, a £599 spread on the same certified stone. MOH London lists it at £834. 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.
