Listed at 4 retailers as of October 31, 2026, with prices from $13,975 to $20,083, a $6,109 spread on the same certified stone. Zales lists it at $20,083. 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.
