Why is our conversion rate so low?

Hi Friends:

I would really love to get some honest constructive feedback on our jewelry store. Our conversion rate is rather terrible at 0.26%.

Seriously, any constructive feedback would be great, and deeply appreciated.

We have hired a person to do our advertising, spend about $1k per month on ads, and try to stay engaged on social media.
