Listed at 11 retailers as of October 29, 2026, with prices from €1,164 to €4,739, a €3,576 spread on the same certified stone. MOH London lists it at €4,739. 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.
