Listed at 24 retailers as of October 31, 2026, with prices from €311 to €2,918, a €2,607 spread on the same certified stone. Brilliant Earth lists it at €2,918. 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.
