Listed at 25 retailers as of November 2, 2026, with prices from €728 to €4,083, a €3,355 spread on the same certified stone. Brilliant Earth lists it at €4,083. 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.
