Yes, it is a saturated market so you will need to be patient and hardworking. It takes time to get found. Keep improving your photos. You need more natural light. Try to take photos in the day near an open window or use fun cups or old books as photo props.
Also, keep trying to utilize your tags.

You can use "pearl dangles" "pearl baubles" etc... Try to find a style of your pieces like "french country" or "modern". Dont get too discouraged. You are doing fine!!
