Listed at 14 retailers as of November 5, 2026, with prices from $1,898 to $5,017, a $3,119 spread on the same certified stone. NZ Jewellers lists it at $5,017. 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.
