Listed at 10 retailers as of November 6, 2026, with prices from €202 to €1,379, a €1,177 spread on the same certified stone. Brilliant Earth lists it at €1,379. 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.
