Listed at 18 retailers as of November 4, 2026, with prices from €297 to €1,341, a €1,044 spread on the same certified stone. Reve Diamonds lists it at €1,341. 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.
