Listed at 16 retailers as of November 4, 2026, with prices from €234 to €1,239, a €1,005 spread on the same certified stone. Reve Diamonds lists it at €1,239. 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.
