Listed at 17 retailers as of October 30, 2026, with prices from £985 to £3,101, a £2,116 spread on the same certified stone. NZ Jewellers lists it at £3,101. 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.
