Listed at 13 retailers as of October 28, 2026, with prices from £9,941 to £31,757, a £21,816 spread on the same certified stone. Yorxs lists it at £31,757. 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.
