Listed at 21 retailers as of October 30, 2026, with prices from €720 to €3,446, a €2,726 spread on the same certified stone. Brilliant Earth lists it at €3,446. 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.
