About this 1ct natural round diamond

Listed at 17 retailers as of November 5, 2026, with prices from $1,880 to $6,100, a $4,220 spread on the same certified stone. NZ Jewellers lists it at $6,100. 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.
