This 4.31ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG752509904 or 752509904. Listed at 4 retailers as of October 31, 2026, with prices from £3,528 to £5,075, a £1,547 spread on the same certified stone. Kay Jewelers lists it at £5,075. 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.
