About this 1ct natural round diamond

Listed at 22 retailers as of November 4, 2026, with prices from $3,254 to $8,970, a $5,715 spread on the same certified stone. NZ Jewellers lists it at $8,970. 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.
