Listed at 9 retailers as of October 27, 2026, with prices from €555 to €3,436, a €2,881 spread on the same certified stone. MOH London lists it at €3,436. 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.
