Listed at 6 retailers as of November 4, 2026, with prices from €339 to €2,076, a €1,737 spread on the same certified stone. Brilliant Earth lists it at €2,076. 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.
