Listed at 20 retailers as of November 4, 2026, with prices from €184 to €1,082, a €898 spread on the same certified stone. Reve Diamonds lists it at €1,082. 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.
