About this 1.33ct lab-grown cushion diamond

This 1.33ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG555298818 or 555298818. Listed at 10 retailers as of October 25, 2026, with prices from £142 to £818, a £676 spread on the same certified stone. MOH London lists it at £818. 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.
