This 1.54ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG681546230 or 681546230. Listed at 14 retailers as of November 3, 2026, with prices from £373 to £1,467, a £1,093 spread on the same certified stone. Brilliant Earth lists it at £1,467. 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.
