Listed at 13 retailers as of November 1, 2026, with prices from €485 to €2,511, a €2,026 spread on the same certified stone. MOH London lists it at €2,511. 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.
