Listed at 15 retailers as of November 4, 2026, with prices from $630 to $2,617, a $1,987 spread on the same certified stone. NZ Jewellers lists it at $2,617. 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.
