About this 1ct natural heart diamond

Listed at 4 retailers as of November 1, 2026, with prices from €2,416 to €5,051, a €2,635 spread on the same certified stone. NZ Jewellers lists it at €5,051. 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.
