About this 1.01ct natural round diamond

Listed at 16 retailers as of November 5, 2026, with prices from $2,323 to $7,015, a $4,693 spread on the same certified stone. NZ Jewellers lists it at $7,015. 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.
