I remember pop beads from when I was a child. Even then, I was interested in anything that I could turn into jewelry. For the uninitiated, pop beads look like this:
It’s obvious, I suppose, but one side fits into the other and you can make a beaded chain of sorts. They get their name from the sound they make joining and disengaging.
Clever jewelry designer Olivia de Soira has played upon the suggestiveness of this shape by pairing two of them together in this ring:

I think that this piece clearly borders art jewelry. I think it shows a lot of humor and inventiveness. In addition to that, though, there is more than just some repurposing going here. There is the subversion of toy jewelry for children and turning it into jewelry for adults or, depending on how you view the piece, adult jewelry.
Addendum: Olivia informed me that she’ll be phasing out her website but you can purchase her jewelry through her Etsy store, DeSoriaDeSign.

that is some well developed ring.
My sister had these pop beads. Something chewed a bunch of them up. Big teeth marks disfigured the beads and twisted the connectors, I can not remember if we had a dog at that time either.
Maybe you did it.
I think I would have remembered that.
why thank you!
Wonderful jewelry blog.
I am phasing out my website, feel free to see new things on my etsy store:

You’re welcome. Thank you for the kind words. I’ll edit the piece to add an Etsy link.
