Listed at 8 retailers as of October 29, 2026, with prices from €628 to €2,862, a €2,234 spread on the same certified stone. MOH London lists it at €2,862. 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.
