About this 1.35ct lab-grown cushion diamond

This 1.35ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG553246405 or 553246405. Listed at 11 retailers as of November 2, 2026, with prices from £143 to £820, a £677 spread on the same certified stone. MOH London lists it at £820. 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.
