Welcome to the Team.
I am not an expert by any means, but here goes my opinion.
First of all, your jewelry is beautiful.
I will try to offer some ideas based on advice I have received in the past and articles I have read.
One thing I noticed is that in your description you offer your e-mail addres and encourage your prospective customer to contact you by e-mail. You may want to rethink that approach. It is best – and I believe Etsy encourages this – to have all communications through convos. This is for your own protection (just in case there is a disagreement or misunderstanding).
On your store front, the following photo is cut off at the bottom. You may want to re-size it to fit the space allowed:

Some of the photos of your stand-alone jewelry are too light and seem over-exposed. Example:

In my opinion, the jewelry gets outstaged by the model in the small pictures. I would suggest that your first photo is that of the piece of jewelry itself, without distractions. For example, in this photo your earrings get lost.

For example if your title is: Multi Strand Necklace Made with Swarovski Pearls and Ombre Crystals Silver Chain Toggle Clasp
Your tags should be something like: multi strand necklace, Swarovski pearls, pearl necklace, Swarovski crystals, necklace with crystals, ombre crystals, toggle clasp necklace, silver chain necklace, or something like that.
Some people recommend that you include the name of your shop in your tags.
I am very tired, hard day, but I hope the above is of some help to you.
I wish you a lot of success and many, many sales.
