Listed at 17 retailers as of November 1, 2026, with prices from €139 to €1,337, a €1,198 spread on the same certified stone. Do Amore Diamonds lists it at €1,337. 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.
