Listed at 17 retailers as of November 3, 2026, with prices from $3,888 to $15,723, a $11,836 spread on the same certified stone. Taylor and Hart lists it at $15,723. 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.
