This 1.04ct lab-grown cushion sits in the classic one-carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by GCAL 312850387. Listed at 7 retailers as of November 5, 2026, with prices from £216 to £843, a £626 spread on the same certified stone. MOH London lists it at £843. 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.
