Listed at 4 retailers as of October 28, 2026, with prices from $912 to $1,615, a $704 spread on the same certified stone. Jared lists it at $1,615. 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.
