This 1.3ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG822622856 or 822622856. Listed at 16 retailers as of November 1, 2026, with prices from £253 to £1,136, a £883 spread on the same certified stone. Reve Diamonds lists it at £1,136. 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.
