Listed at 24 retailers as of October 27, 2026, with prices from $11,258 to $24,420, a $13,161 spread on the same certified stone. NZ Jewellers lists it at $24,420. 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.
