Listed at 20 retailers as of October 30, 2026, with prices from €379 to €2,453, a €2,074 spread on the same certified stone. Brilliant Earth lists it at €2,453. 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.
