Sims Keychain?

[dexstarr.livejournal.com]

I've been racking my brain trying to think of places to find what I want, but I've come up with nothing so far, so I thought I'd ask this and hopefully get some help.

I want to make a keychain of the Sims green plumbob, example picture at the bottom. But I can't find a suitable green plumbob thingy. I want it to be of decent size - not tiny - green, and translucent. I've tried searching for plumbobs, green beads, green diamond shapes, etc, without any luck.

Anyone have any ideas of what I could search for, or better yet, know any places online where I could buy something like this? Thanks muchly!
