Listed at 13 retailers as of October 30, 2026, with prices from €505 to €4,484, a €3,980 spread on the same certified stone. Do Amore Diamonds lists it at €4,484. 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.
