This 1.31ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG724598885 or 724598885. Listed at 4 retailers as of October 30, 2026, with prices from £555 to £769, a £213 spread on the same certified stone. Zales lists it at £769. 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.
