Listed at 21 retailers as of October 25, 2026, with prices from $3,861 to $8,751, a $4,890 spread on the same certified stone. NZ Jewellers lists it at $8,751. 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.
