Listed at 17 retailers as of November 5, 2026, with prices from £1,228 to £3,433, a £2,205 spread on the same certified stone. NZ Jewellers lists it at £3,433. 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.
