Listed at 6 retailers as of November 1, 2026, with prices from £1,291 to £3,457, a £2,166 spread on the same certified stone. NZ Jewellers lists it at £3,457. 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.
