Listed at 2 retailers as of October 30, 2026, with prices from $6,369 to $11,938, a $5,569 spread on the same certified stone. Brilliance lists it at $11,938. 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.
