FINALLY SOMEONE ELSE NOTICED THIS.

But also, I have another head canon involving that... The gems are not just for "show" but also there in case of an emergency. Since they are probably darkstone and darkstone seemingly powers quite a bit of things, it is basically like them carrying an extra set of batteries inconspicuously if they have equipment that needs it (probably hand held lanterns or cannoneer's harpoon/s). That would also be another reason why boatswain has a lot of them since they are the one who make most repairs on the ship (also including some equipment).

It's just another reason why boatswain's cape sooooo much. I like my gems :D

Also, a little rant. I remember a conversation I had with someone when the season was live. They kept crapping on the cape colors not matching thus claiming that the capes didn't have a cohesive theme until I pointed out the gems (they didn't notice that.) And I also explained that it actually made sense for them to have different cape colors since (a) The spirits working in the crew are probably are from different areas and walks of life (b) would be able to tell who is who from a distance which could be useful in certain situations. Anyway, the convo opened the person's eyes to the capes and, yes, matching cape colors isn't everything people!!!! Other design themes and elements EXIST.

Hi!! Abyss crew love time. I just spotted something GREAT, and now own a new hc. Anyways.

Look! At! This!!!! They all have a Gem (yeah I know it's probably darkstone but still. I'm calling them gems)!!! Of course, this can be interpreted in a few ways, but as the person I am I can only see it in one way: acknowledgement that you're part of the crew- part of the family. They deserve that!!!

Anyways. Since Boatswain has the most gems, I think that they're the ones who make them. That headcannon kinda fell down to "they are longtime friends with Commodore, who trusts their judgement with distribution of the gems and safekeeping of loot" because why not!! And! They could also be the first mate of the crew! Among other things!!!

And of fucking course this means I'm finding a nice spot for my own skykid to wear a gem lmao. (I say, as I modify how her wristband looks like)
