Listed at 15 retailers as of October 30, 2026, with prices from €192 to €1,835, a €1,643 spread on the same certified stone. Do Amore Diamonds lists it at €1,835. 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.
