Listed at 13 retailers as of November 1, 2026, with prices from $1,261 to $3,320, a $2,059 spread on the same certified stone. NZ Jewellers lists it at $3,320. 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.
