Listed at 16 retailers as of October 27, 2026, with prices from €614 to €4,333, a €3,719 spread on the same certified stone. Brilliant Earth lists it at €4,333. 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.
