Listed at 7 retailers as of October 30, 2026, with prices from €1,495 to €3,493, a €1,998 spread on the same certified stone. With Clarity lists it at €3,493. 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.
