About this 0.4ct natural radiant diamond

Listed at 3 retailers as of October 27, 2026, with prices from $624 to $745, a $120 spread on the same certified stone. Michael Trio lists it at $745. 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.
