Listed at 2 retailers as of November 3, 2026, with prices from £3,089 to £3,947, a £858 spread on the same certified stone. Yorxs lists it at £3,947. 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.
