They are a mess. The main problem is mistagging where users somehow tag pendant on things that are integrated rather than hanging or attached or things that are attached to something that's not neckwear. There is also probably a redundancy issue.
- bracelet pendant: if we go by the whole "attached to neckwear" definition, this tag should probably be charm bracelet instead though the bracelet currently tagged bracelet_pendant doesn't seem very similar to the other charm bracelets.
- pendant earring: should be pendant earrings instead. Also, maybe the only legit pendant tag for non-neckwear?
- pendant watch: lots of mistags. People tagged this on normal pocket watch or when the watch is attached to things other than neckwear. I still think this should at least imply pocket watch.
- pendant removed: this seems to be just unworn necklace
- heart pendant, cross pendant, etc: these tags sound like they can overlap a lot with something like heart necklace, heart choker, or heart collar.
- gold pendant, red pendant, etc: Basically colored pendant tags, I don't think these are really necessary.
