About this 0.5ct natural oval diamond

Listed at 11 retailers as of November 5, 2026, with prices from £311 to £1,293, a £982 spread on the same certified stone. NZ Jewellers lists it at £1,293. 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.
