Listed at 15 retailers as of October 26, 2026, with prices from €204 to €1,096, a €892 spread on the same certified stone. MOH London lists it at €1,096. 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.
