Listed at 9 retailers as of October 30, 2026, with prices from £1,265 to £3,623, a £2,358 spread on the same certified stone. NZ Jewellers lists it at £3,623. 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.
