Listed at 8 retailers as of October 29, 2026, with prices from €361 to €1,570, a €1,209 spread on the same certified stone. MOH London lists it at €1,570. 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.
