Seashell/Ocean Inspired Jewelry

I am working on making a mermaid costume. (It isn't done yet, but I've made a few sketches and have played with a few ideas.) While in thise thought process I made some ocean themed jewelry with a selection of shells and some small glass beads from blues, green, and ambers.
