This 1.52ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG472177462 or 472177462. Listed at 6 retailers as of November 4, 2026, with prices from £353 to £826, a £473 spread on the same certified stone. MOH London lists it at £826. 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.
