Listed at 31 retailers as of October 30, 2026, with prices from $16,125 to $76,291, a $60,167 spread on the same certified stone. With Clarity lists it at $76,291. 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.
