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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG618498649 or 618498649. Listed at 8 retailers as of November 4, 2026, with prices from £274 to £898, a £624 spread on the same certified stone. MOH London lists it at £898. 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.
