There is quite alot of items that is marked as treasure.

But, if an item is marked as treasure, you cannot see where the item is worn... :/

Can you make the identify / lore function, so it adds the worn location?

a bracelet of spider chitin can be referred to as
'bracelet spider chitin circle'.
It is worth 200 copper, and is of the 35th level of power.
It is a treasure.
It is made of bone and weighs 0 pounds 2 ounces.

So it reflects :

It is armor worn on the feet.

Or

It is treasure worn on the feet.
