Listed at 6 retailers as of October 30, 2026, with prices from $3,435 to $7,841, a $4,407 spread on the same certified stone. NZ Jewellers lists it at $7,841. 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.
