Listed at 5 retailers as of October 25, 2026, with prices from €434 to €1,496, a €1,062 spread on the same certified stone. MOH London lists it at €1,496. 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.
