I assume you mean the gold necklace/jewellry etc (b/c gold, reagents are obvi). They are used to complete the Artifacts (see tab to the right of the Collections tab). If you complete a lot of collections and only a few Artifacts you will accumulate a boat-ton of these and there is no other use for them. Unless a Friend puts it in their WL - then you can gift them away.
