Listed at 18 retailers as of November 5, 2026, with prices from £1,285 to £3,595, a £2,309 spread on the same certified stone. NZ Jewellers lists it at £3,595. 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.
