Listed at 10 retailers as of October 29, 2026, with prices from €237 to €910, a €673 spread on the same certified stone. MOH London lists it at €910. 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.
