Listed at 6 retailers as of November 1, 2026, with prices from €2,619 to €7,332, a €4,713 spread on the same certified stone. MOH London lists it at €7,332. 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.
