(A necklace might be neat, depending on how small it is maybe a ring even. I myself wouldn’t paint it or add anything to the skull itself (like jewels or any of that), I’d suggest letting it stay natural and awesome on it’s own :D)

(It’s the same length as my thumb, so a fairly decent size. The resin color makes it a bit yellowed, like it’s aged. So it looks natural. Good idea :D Thank you!)
