Listed at 7 retailers as of October 29, 2026, with prices from $851 to $6,495, a $5,644 spread on the same certified stone. Frank Darling lists it at $6,495. 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.
