Listed at 15 retailers as of November 5, 2026, with prices from $2,163 to $5,801, a $3,638 spread on the same certified stone. NZ Jewellers lists it at $5,801. 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.
