About this 0.4ct natural cushion diamond

Listed at 14 retailers as of October 28, 2026, with prices from $615 to $1,394, a $779 spread on the same certified stone. MOH London lists it at $1,394. 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.
