Listed at 11 retailers as of October 29, 2026, with prices from €451 to €2,314, a €1,863 spread on the same certified stone. MOH London lists it at €2,314. 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.
