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 standard cut grade and certified by IGI LG695525991 or 695525991. Listed at 8 retailers as of November 4, 2026, with prices from £293 to £1,516, a £1,223 spread on the same certified stone. Do Amore Diamonds lists it at £1,516. 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.
