About this 0.9ct natural emerald diamond

Listed at 13 retailers as of October 28, 2026, with prices from £862 to £2,246, a £1,384 spread on the same certified stone. NZ Jewellers lists it at £2,246. 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.
