Listed at 17 retailers as of November 4, 2026, with prices from $4,075 to $8,296, a $4,221 spread on the same certified stone. NZ Jewellers lists it at $8,296. 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.
