Listed at 11 retailers as of October 30, 2026, with prices from £537 to £1,826, a £1,289 spread on the same certified stone. NZ Jewellers lists it at £1,826. 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.
