Listed at 11 retailers as of October 31, 2026, with prices from €394 to €2,873, a €2,479 spread on the same certified stone. Brilliant Earth lists it at €2,873. 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.
