About this 1.13ct lab-grown cushion diamond

This 1.13ct 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 LG648417772 or 648417772. Listed at 4 retailers as of November 5, 2026, with prices from £451 to £639, a £188 spread on the same certified stone. Kay Jewelers lists it at £639. 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.
