Listed at 3 retailers as of November 2, 2026, with prices from €400 to €2,453, a €2,053 spread on the same certified stone. Diamond Exchange Canada 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.
