I like it when Etsy does the shopping work for me. I found these awesome geometric necklaces, by BlueBird Lab, in my "Handpicked Items" and now I would like to have them all.
There are regular ones and special limited editions, like the one above.
I cannot really tell what is going on with the clasp, but I love the way it looks. It seems like it might also be adjustable? Always a bonus.
You should, of course, buy several and wear them all at once. Also, they are from Lithuania, so you can be all, "Oh, these? They're from my jeweler in Lithuania."
