Listed at 13 retailers as of November 5, 2026, with prices from $4,237 to $9,517, a $5,280 spread on the same certified stone. NZ Jewellers lists it at $9,517. 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.
