About this 0.9ct natural oval diamond

Listed at 13 retailers as of November 5, 2026, with prices from £888 to £2,255, a £1,367 spread on the same certified stone. NZ Jewellers lists it at £2,255. 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.
