Listed at 15 retailers as of October 29, 2026, with prices from €189 to €1,137, a €948 spread on the same certified stone. Brilliant Earth lists it at €1,137. 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.
