This 1.52ct 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 LG787623226 or 787623226. Listed at 14 retailers as of October 29, 2026, with prices from £643 to £2,911, a £2,267 spread on the same certified stone. Brilliant Earth lists it at £2,911. 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.
