Listed at 6 retailers as of October 30, 2026, with prices from $2,467 to $6,604, a $4,137 spread on the same certified stone. NZ Jewellers lists it at $6,604. 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.
