About this 1.02ct natural round diamond

Listed at 16 retailers as of November 5, 2026, with prices from £1,147 to £3,342, a £2,195 spread on the same certified stone. NZ Jewellers lists it at £3,342. 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.
