Listed at 6 retailers as of November 4, 2026, with prices from £169 to £673, a £504 spread on the same certified stone. NZ Jewellers lists it at £673. 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.
