Listed at 25 retailers as of October 29, 2026, with prices from $4,086 to $18,149, a $14,063 spread on the same certified stone. Brilliant Earth lists it at $18,149. 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.
