Listed at 11 retailers as of November 4, 2026, with prices from €430 to €3,941, a €3,511 spread on the same certified stone. Brilliant Earth lists it at €3,941. 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.
