Listed at 7 retailers as of November 2, 2026, with prices from $3,331 to $7,719, a $4,388 spread on the same certified stone. NZ Jewellers lists it at $7,719. 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.
