Listed at 11 retailers as of November 4, 2026, with prices from €526 to €3,189, a €2,663 spread on the same certified stone. MOH London lists it at €3,189. 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.
