Listed at 14 retailers as of November 4, 2026, with prices from €376 to €3,074, a €2,698 spread on the same certified stone. Brilliant Earth lists it at €3,074. 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.
