Listed at 16 retailers as of October 28, 2026, with prices from €199 to €1,298, a €1,099 spread on the same certified stone. Brilliant Earth lists it at €1,298. 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.
