Listed at 15 retailers as of October 30, 2026, with prices from €665 to €2,800, a €2,135 spread on the same certified stone. NZ Jewellers lists it at €2,800. 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.
