Listed at 4 retailers as of November 4, 2026, with prices from £1,680 to £3,322, a £1,642 spread on the same certified stone. MOH London lists it at £3,322. 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.
