Listed at 11 retailers as of October 29, 2026, with prices from €439 to €3,622, a €3,183 spread on the same certified stone. MOH London lists it at €3,622. 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.
