Listed at 15 retailers as of October 26, 2026, with prices from $652 to $4,717, a $4,065 spread on the same certified stone. Brilliant Earth lists it at $4,717. 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.
