Listed at 14 retailers as of November 4, 2026, with prices from €404 to €2,144, a €1,740 spread on the same certified stone. Helzberg Diamonds lists it at €2,144. 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.
