About this 1.09ct lab-grown cushion diamond

This 1.09ct lab-grown cushion sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GCAL 330250003. Listed at 6 retailers as of November 2, 2026, with prices from £136 to £778, a £642 spread on the same certified stone. MOH London lists it at £778. 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.
