Does anyone else use gems?

I wear amber studs in my cheek and tragus piercings and own amber beads for my others' captives, though that's more because I think amber looks pretty. There's definitely an attractive quality to be seen that goes beyond appearance, however, which most likely stems from what amber's associated with (like that scene in Jurassic Park). It's sorta like carrying around something with a long history, like an heirloom passed down by nature herself.
