I don't wear athiest jewelry because it's something I've been my whole life and it's a part of who I am anyway. I don't feel like I need to 'advertise' who I am I guess. I used to have a Darwin amphibian (Jesus fish spin off from evolve fish) bumper sticker and the church near my house complained :-/

I started putting together a charm bracelet with as many religious symbols that I could find. But people really did get offended, so it's been disbanded

I have an American Atheist Life Member pin I wear on the lapel of my sport coats/suit coats whenever I wear them, which - living in SW FL - I don't often do, but I also have a number of AA tee shirts which I wear often.

The nearest that I have is a silver ankh, which for me symbolizes life

I wear my crescent moon necklace all the time. I have had it for about 15 years. It was made for me. It has a scattering of stars and a spiral on the back of it. I love it and never take it off. I wear earrings all the time, and I wear several rings. I have a bracelet that also has a moon and stars, one that is an antique and one that is made out of my horses tail hairs. They aren't atheist, but they are science type. I know it isn't jewelry, but I one of my tattoos, is a nautalus, representing the Fibonacci Sequence. I admit that I am pagan, albiet an atheist pagan, so my jewelry reflects that.

No.
But I do have a box of jewelry - rings, bracelets, pins.
Not big on necklaces - don't like things around my neck.
Never wear a tie either.

I don't wear any jewelry except for a black and purple titanium band on my right hand. Doesn't mean anything, I just like it.
I don't want any bumper stickers or symbols on my car because people are evil, and will deface it.

I had this wonderful bumper sticker that said "Born OK the first time" , and some dang person ripped it off.

YES. I wear a diamond nothing surrounding a silver nothing hanging from a gold nothing around my nothing. I think it looks beautiful and fits all sizes. the perfect symbol for belief in nothing.

No. Atheism isn't what I'd call an important part of my life; I don't think about it often, day to day. I don't need a reminder that I'm an atheist, it's mostly just a useful label.

I would consider a bumper sticker, though.

Have a pin with an American flag and the words Free Thinker. Have it pinned on a baseball cap but I seldom wear caps these days.

Like what would that even look like? Do not believe I ever saw or heard of jewelry like that...a cross inside on of those "no" symbols? (The circle with the slash across it)
Describe, please, and where to obtain

My car does, but I do not yet aside from general apparel.
