Listed at 18 retailers as of October 30, 2026, with prices from €542 to €4,816, a €4,273 spread on the same certified stone. Do Amore Diamonds lists it at €4,816. 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.
