Listed at 15 retailers as of November 1, 2026, with prices from $5,604 to $10,998, a $5,394 spread on the same certified stone. NZ Jewellers lists it at $10,998. 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.
