I found one of those "What's your Mermaid Name" things, you choose from a list according to the first letter of your first name, the last digit of your phone number (modern times! lol) and your birth month and the result can be lame but works with this picture!

"Pearl Crystal Shell"

Considering the crystals by Clover on my chest, the pearls on my hands by Andore and my headband by Swan, I think this name nails it! ♥
