This 1.52ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG803667043 or 803667043. Listed at 18 retailers as of October 28, 2026, with prices from £187 to £1,539, a £1,352 spread on the same certified stone. Brilliant Earth lists it at £1,539. 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.
