This 4.05ct 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 LG790642725 or 790642725. Listed at 16 retailers as of October 31, 2026, with prices from £518 to £4,023, a £3,505 spread on the same certified stone. Do Amore Diamonds lists it at £4,023. 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.
