Is there any meaning to the snake symbol? Absolutely! So much that it's hard to fit into a short answer. So many cultures use snakes in their mythologies that legends and stories abound. In general though, snakes are associated with hidden mysteries, transformation and renewal, knowledge, and healing. I encourage you to do your own research into this fascinating topic.
Is this ring unisex? I'm a big believer in men and women wearing whatever the hell they want, regardless of what "society" says, so I'm probably not the best person to ask. But I can tell you, there's nothing "girlie-girl" about this ring. It is simple, strong, and stylish, no matter whose hand it is on. That being said, it is only available up to a size 9, and the band is only 1/16" wide. This may not be the best choice if you have large hands.
Do you have more realistic snake jewelry? Yep! We know that not everyone is looking for such an abstract, stylized looking snake. If you want something more life-like, check out our Coiled Silver Snake Ring and Large Silver Snake Ring.
