Listed at 11 retailers as of November 1, 2026, with prices from €363 to €1,760, a €1,397 spread on the same certified stone. MOH London lists it at €1,760. 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.
