Listed at 16 retailers as of October 26, 2026, with prices from $4,018 to $17,388, a $13,370 spread on the same certified stone. With Clarity lists it at $17,388. 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.
