Listed at 5 retailers as of October 31, 2026, with prices from £4,130 to £18,919, a £14,789 spread on the same certified stone. Adiamor lists it at £18,919. 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.
