It should have something akin to the rust monster’s armor destruction effect. DC 15 con save on contact. If you fail, your nonmagical bones are weakened and your AC is reduced by 1. Fail 5+con mod saves and your bones are consumed and you become a puddle of skin-wrapped organs and muscles.
tl;dr The "default" presentation of Adamantine Armor in the DMG is a magic item, the "default" presentation of adamantine weapons in Xanathar's is they're nonmagical.
Personally, I'd say that since it's an imaginary material with supernatural properties, it's inherently magical and thus anything made from it is too but that's just me making sense 🤷
Your bones require enchantment for protection. It becomes a common practice for the area because of the prevalence of bone faes in the world. The enchantments are very prevalent in society, so the bone faes are starved and extra aggressive. Not having protection make you a very noticeable target and almost always means certain death.
The enchantment requires upkeep and only a few casters in the area can provide the enchantments. The initial enchantment is very expensive and requires special materials, so the enchanters offer payment plans to enable commoners to get the protection they need. If you miss too many payments, they have to repossess your bones. Cue opera music.
There's a movement for Universal Socialized Bone Enchantment Upkeep but the enchanters are making money and the alchemists who produce the special materials are making money, and the people mostly just want to get through the harvest, so even though this King or that sometimes talks about getting a functional program up and running, it's hard to believe that it's really going to happen, even though literally every other developed kingdom in the world has Universal Bone Enchantment Upkeep.

Wait… Who the hell has the magical bones?!

But not the claws, since adamantine weapons aren't magical, but adamantine armor is.
Huh? Is that a real rule? 🤨
Sort of, but more just mocking a small inconsistency in the default presentation of the items. In the DMG is the magic item Adamantine Armor, but that doesn't necessarily mean all armor made with adamantine is magical, that's just a specific example they've provided. Likewise in Xanathar's Guide we got rules for weapons made with adamantine. They are not inherently magical but that doesn't mean you couldn't have a magic weapon made of adamantine, that's just not a specific example they provide directly in the rules on adamantine weapons. You can view more discussion on it here https://rpg.stackexchange.com/questions/92657/are-weapons-and-armor-made-of-mithral-or-adamantine-considered-magical and here https://www.sageadvice.eu/why-is-an-adamantine-armor-a-magical-item-while-a-adamantine-weapon-is-just-one-made-with-a-diferent-material/ as well as reddit, xitter, etc.

Thanks for the explanation 🙂

Dave. He's cool.
Not Dave from accounting though. That guy sucks. His bones are subpar too.
Wait, you guys are getting magical bones?
I suppose aasimar and tieflings might have naturally magical bones…
And if Gale from Baldurs Gate 3 is anything to go by, wizards have magical boners.
As long as they put on their…
…robe and wizard hat?
Maybe turn the puddles into undead minions, if I recall correctly there's a monster that is just flesh and organs reanimated

A bone reposessor huh? An opera? Sounds like it could a bonetic opera, perhaps.
