Firstly, I don't recall any gem ever appearing in Hashi's forehead, maybe, only except for the forehead marking of his Sage Mode. Secondly, there hasn't ever been mentioned any "Haruno clan", it just seems to be a family name of Sakura and her relatives. Not every character has to come from some clan, there surely can be clanless ones, like Sakura herself or Minato.
