About this 0.8ct natural heart diamond

Listed at 7 retailers as of November 1, 2026, with prices from $1,070 to $2,046, a $976 spread on the same certified stone. MOH London lists it at $2,046. 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.
