9 Multi-Functional Jewelry Pieces That Will Amaze You

Our jewelry is basically our armor. It can update an outfit, make a statement (like, "Hey, world! I'm engaged!") and give us all a little bit of bling-induced confidence when we need it most. But as amazing as jewelry can be on its own, some pieces go way above and beyond with two-for-one functions that will blow your mind. Enter: Multi-furpose jewelry.

Sure, a necklace is great and pretty and whatever… but a necklace that doubles as a vibrator? Or as a full-blown weapon? Now, we’re talking. There is honestly nothing better than when fashion and function come together to create pieces we actually want to wear and use, and multi-purpose jewelry does exactly that. Some of it helps make our lives easier (like a phone charging bracelet) while others are straight-up badass (like the aforementioned “necklace knife.”)

Regardless of their intended use (or, in almost all of these cases, uses), these nine pieces of multi-functional jewelry will not only upgrade your wardrobe, but will basically change your life. After seeing these sneaky, yet stylish items, you’ll never want to buy a regular old necklace/ring/bracelet ever again.
