Listed at 5 retailers as of October 30, 2026, with prices from $4,759 to $8,290, a $3,532 spread on the same certified stone. NZ Jewellers lists it at $8,290. 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.
