Listed at 5 retailers as of October 29, 2026, with prices from €383 to €1,037, a €654 spread on the same certified stone. MOH London lists it at €1,037. 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.
