Could this ring be used as a wedding ring? It isn't going to look like a traditional wedding ring, but then, that's not what you're after, is it? Choose the ring that resonates most closely with what is in your heart. If this is the ring for you, you'll know it.
It looks flimsy. Is it going to bend when I wear it? The Silver Vine Ring's filigree pattern certainly gives it an open and airy look, but it actually is surprisingly sturdy. That being said, if you sling cinderblocks around for a living, or wrestle with bears on a regular basis, you might want to put it on a chain around your neck until you are done working with your hands. Any ring can bend if enough force is applied to it. Just use common sense and you should be fine.
Do vines have a symbolic meaning? Vines are unusual members of the plant world. Where most plants rely on their roots to anchor them in place, vines establish their base, but then they grow, and grow, and GROW! And with each step, they reach out to establish footholds and make connections, forming a rich network of support as they make their way.
