About this 1ct natural princess diamond

Listed at 11 retailers as of November 4, 2026, with prices from $2,183 to $5,845, a $3,662 spread on the same certified stone. NZ Jewellers lists it at $5,845. 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.
