Listed at 6 retailers as of November 2, 2026, with prices from $2,749 to $6,279, a $3,530 spread on the same certified stone. NZ Jewellers lists it at $6,279. 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.
