Hi Sarah! I love your rings - they are beautiful! I'm in the same boat, being new to Etsy, but I would say one thing that has helped me get exposure is matching titles with tags, and making sure that the first few words in your title are how someone would search for it, like "wire wrapped ring", or the kind of stone you're using. For the most part, I think you're doing that. Your photo lighting is great - maybe you could use the same background for each photo, like a neutral backdrop, and be sure there is no glare from the sun. I think the ribbons (for breast cancer, etc.) are great.
And others may challenge me on this, but I might suggest bumping up your pricing a little bit. There is a weird psychology to pricing, and if something is priced too low, people may feel that it is not valuable, which is obviously not the case. I think, for example, the purple sodalite ring looks a bit more expensive than it is priced.
I hope that helps! I'd love your input on my shop, too! :)
