Listed at 15 retailers as of November 5, 2026, with prices from €466 to €1,968, a €1,502 spread on the same certified stone. With Clarity lists it at €1,968. 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.
