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 LG816615493 or 816615493. Listed at 15 retailers as of October 29, 2026, with prices from £541 to £2,717, a £2,176 spread on the same certified stone. Brilliant Earth lists it at £2,717. 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.
