Listed at 4 retailers as of November 2, 2026, with prices from $8,430 to $11,427, a $2,997 spread on the same certified stone. Yorxs lists it at $11,427. 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.
