This 1.53ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG787621487 or 787621487. Listed at 13 retailers as of November 2, 2026, with prices from £650 to £2,921, a £2,271 spread on the same certified stone. Brilliant Earth lists it at £2,921. 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.
