Listed at 16 retailers as of November 1, 2026, with prices from $5,790 to $24,828, a $19,038 spread on the same certified stone. With Clarity lists it at $24,828. 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.
