Looks like badge of unknown civil association the name of which started with 土.

Marked "pure silver" and "gilded".

Thanks a lot again, JapanX! I hoped, it was a plane, not  "土"... It is just 1  sm in length, but has two pleasant marks... Besides, the stopper ring is not a simple one.

Badge with the heart has "聖 - holy" - some japanese christian association.

Others look like school badges.
