Hammer Identity?

[brandowelsh]

Can anyone help me with a hammer identification? It’s generally purple in color during the day and almost bluish-green under actinic light. Apologies for the snail in the first picture. Of course he had to be there when I wanted to post this.

It's a hammer. Pick your name, lol.

Fimbriaphyllia cf paraancora. No need for trade names; they're just there to bump up the price anyway
