About this 1.03ct lab-grown cushion diamond

This 1.03ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG607307491 or 607307491. Listed at 10 retailers as of November 1, 2026, with prices from £139 to £793, a £654 spread on the same certified stone. MOH London lists it at £793. 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.
