About this 1.3ct natural cushion diamond

Listed at 7 retailers as of October 31, 2026, with prices from €1,843 to €2,648, a €805 spread on the same certified stone. Blue Nile lists it at €2,648. 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.
