Listed at 4 retailers as of November 5, 2026, with prices from €2,453 to €3,314, a €862 spread on the same certified stone. Kay Jewelers lists it at €3,314. 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.
