On the Armor 2.0 reveal stream they showed only eververse ornaments were universal, but here's proof after reacquiring the IB set from CoO, I can apply them to any armor.

This is likely a bug, but I'm hoping we can all come together and show our appreciation for it and hopefully Bungie won't remove it. We all were saying it would be cool if it worked this way. There's really no argument against more customization.

Works with crucible, vanguard, and IB ornaments only. Can't use raid ornaments or any other.

Edit: I'm in class right now, but others are confirming it works as well but it is wonky. I'll do some testing to confirm but I'm sure the people in the comments aren't lying, it seems these things are single unlocks, so you'll have to do it each time you want to apply it to an armour piece.
