Listed at 2 retailers as of October 27, 2026, with prices from $4,653 to $9,150, a $4,497 spread on the same certified stone. Brilliant Earth lists it at $9,150. 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.
