Listed at 10 retailers as of November 5, 2026, with prices from $3,262 to $6,401, a $3,139 spread on the same certified stone. NZ Jewellers lists it at $6,401. 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.
