Listed at 15 retailers as of November 5, 2026, with prices from £507 to £1,725, a £1,218 spread on the same certified stone. NZ Jewellers lists it at £1,725. 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.
