Listed at 7 retailers as of October 29, 2026, with prices from €10,150 to €24,776, a €14,626 spread on the same certified stone. Diamond Quarter lists it at €24,776. 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.
