Listed at 26 retailers as of November 4, 2026, with prices from €166 to €1,598, a €1,432 spread on the same certified stone. Do Amore Diamonds lists it at €1,598. 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.
