Product identity/source of two items in Zahara Hair 2 promos?

Cowrie

I was looking at the promos to the item Zahara Hair 2 for Genesis 8 Female(s), and I noticed a couple of things that look interesting that don't seem to be listed under the additional products used in promo images.

The first of the items I'd like to know the identity of is the beaded collar-type garment worn by both women in the first image and the "background" woman in the second image.  I tried several search terms looking for it (including, but not limited to, beaded, beads and collar), but nothing turned it up.  The other item I'm looking for is the bone-looking earring worn by the same woman in the second image, which I also tried and failed to locate on my own.  So, I'm turning to the community.  Can anyone point me in the direction of either of these two items?
