About this 1.22ct lab-grown cushion diamond

This 1.22ct 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 LG837659073 or 837659073. Listed at 11 retailers as of November 3, 2026, with prices from £283 to £1,260, a £977 spread on the same certified stone. MOH London lists it at £1,260. 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.
