Listed at 4 retailers as of October 29, 2026, with prices from £3,500 to £4,963, a £1,464 spread on the same certified stone. Zales lists it at £4,963. 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.
