Mixed Metal Double Chain Charm Holder Necklace

I bought this to help bring my different metal colors of rings and earrings together- so I can wear both silver and gold at the same time. I like it a lot, and I wear it both on the weekends on the beach and at work. However, it does try to shift around a lot because the gold side is heavier than the silver. But, I dont wear a charm on it. I’m sure if you bought a charm for it, it would help weight it down.
