Listed at 8 retailers as of November 3, 2026, with prices from €241 to €1,673, a €1,433 spread on the same certified stone. Blue Nile lists it at €1,673. 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.
