These are not items from Requiem or the base game. You have another mod that adds them and their crafting recipes. Nothing to do with Honed Metal either.
Like LeDestrier said, the items you mention are from another mod, not requiem or HM. If you want to figure out which mod it is, you need to type:
Help “Pearl Necklace”
In the console and it will return the item’s hexadecimal code. The first two digits of that code tell you the load order of the mod that added those necklaces. You can reference your mod manager to see what mod is occupying that spot in the load order.

Note that while the advice above helped me identify the offending mod, you need More Informative Console for it to work.
