Listed at 16 retailers as of November 5, 2026, with prices from $3,856 to $8,278, a $4,423 spread on the same certified stone. NZ Jewellers lists it at $8,278. 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.
