Listed at 5 retailers as of October 29, 2026, with prices from £478 to £3,483, a £3,004 spread on the same certified stone. Frank Darling lists it at £3,483. 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.
