This 1.54ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG737540245 or 737540245. Listed at 16 retailers as of November 5, 2026, with prices from £387 to £1,998, a £1,610 spread on the same certified stone. MOH London lists it at £1,998. 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.
