Listed at 13 retailers as of October 30, 2026, with prices from $7,400 to $40,798, a $33,397 spread on the same certified stone. Adiamor lists it at $40,798. 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.
