Listed at 16 retailers as of October 31, 2026, with prices from $830 to $8,872, a $8,041 spread on the same certified stone. Brilliant Earth lists it at $8,872. 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.
