Listed at 13 retailers as of November 2, 2026, with prices from $498 to $2,524, a $2,026 spread on the same certified stone. NZ Jewellers lists it at $2,524. 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.
