This 4.55ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG792658548 or 792658548. Listed at 16 retailers as of October 27, 2026, with prices from £479 to £2,873, a £2,394 spread on the same certified stone. Brilliant Earth lists it at £2,873. 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.
