This 1.54ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG726555875 or 726555875. Listed at 18 retailers as of November 4, 2026, with prices from £186 to £1,271, a £1,084 spread on the same certified stone. Brilliant Earth lists it at £1,271. 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.
