Listed at 13 retailers as of November 1, 2026, with prices from $2,161 to $6,769, a $4,608 spread on the same certified stone. With Clarity lists it at $6,769. 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.
