Listed at 9 retailers as of October 30, 2026, with prices from £261 to £1,373, a £1,112 spread on the same certified stone. NZ Jewellers lists it at £1,373. 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.
