About this 1.02ct lab-grown cushion diamond

This 1.02ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG483194854 or 483194854. Listed at 6 retailers as of November 5, 2026, with prices from £292 to £1,244, a £952 spread on the same certified stone. MOH London lists it at £1,244. 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.
