About this 1.2ct natural heart diamond

Listed at 9 retailers as of November 4, 2026, with prices from €3,230 to €6,123, a €2,893 spread on the same certified stone. MOH London lists it at €6,123. 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.
