Listed at 8 retailers as of November 4, 2026, with prices from $3,302 to $6,204, a $2,902 spread on the same certified stone. With Clarity lists it at $6,204. 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.
