Listed at 3 retailers as of November 1, 2026, with prices from €3,587 to €5,693, a €2,106 spread on the same certified stone. MOH London lists it at €5,693. 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.
