Listed at 9 retailers as of October 30, 2026, with prices from $1,651 to $4,202, a $2,551 spread on the same certified stone. NZ Jewellers lists it at $4,202. 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.
