Listed at 12 retailers as of October 31, 2026, with prices from €3,846 to €7,859, a €4,013 spread on the same certified stone. MOH London lists it at €7,859. 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.
