Listed at 16 retailers as of November 5, 2026, with prices from $940 to $3,860, a $2,920 spread on the same certified stone. NZ Jewellers lists it at $3,860. 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.
