Listed at 19 retailers as of November 4, 2026, with prices from €256 to €1,731, a €1,475 spread on the same certified stone. Brilliant Earth lists it at €1,731. 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.
