Listed at 18 retailers as of November 5, 2026, with prices from $3,848 to $10,752, a $6,904 spread on the same certified stone. NZ Jewellers lists it at $10,752. 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.
