Listed at 2 retailers as of October 30, 2026, with prices from £1,691 to £4,215, a £2,524 spread on the same certified stone. Taylor and Hart lists it at £4,215. 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.
