Listed at 8 retailers as of November 5, 2026, with prices from £209 to £1,110, a £901 spread on the same certified stone. NZ Jewellers lists it at £1,110. 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.
