Would you buy this?

I’m a jewelry designer, and I’m trying to start my business by attending craft shows and posting online wherever I can. When I post my stuff on my Facebook, I get wonderfully positive comments about my work, but no one actually ever buys anything. So I’m wondering if it’s a case of “Say something nice because she’s my friend, but UGH.” Or if my prices are too high, or what. I was hoping you would all be kind enough to tell me what you think.

This one is $25

This one is $30 because the pendant is abalone shell, which is actually quite expensive.

These four are all $15.

So, what do you think? No one would ever buy it? Too expensive? Or I’m just overthinking it and should keep on keeping on? I also have cancer awareness bracelets and various earrings. I try to provide lots of variety.
