Listed at 17 retailers as of October 27, 2026, with prices from £207 to £3,327, a £3,119 spread on the same certified stone. Brilliant Earth lists it at £3,327. 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.
