Listed at 26 retailers as of October 30, 2026, with prices from €209 to €2,005, a €1,796 spread on the same certified stone. Do Amore Diamonds lists it at €2,005. 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.
