Listed at 32 retailers as of November 4, 2026, with prices from $932 to $5,401, a $4,469 spread on the same certified stone. With Clarity lists it at $5,401. 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.
