It doesn't mean anything, it's just something I have been wearing for like 10 years now and it's something I'm known for by now and people mention "the girl with the gem" and everyone knows who they got directed to lol :p
I used to wear very plain ones, and only had fancy ones for parties. I nowadays wear fancy ones whenever I go outside, if I know I'm gonna be inside all day I go plain (its just a circle), sometimes I think about stop using them daily and only wear them on special occasions but I'm not ready to give it up just yet :p My fiance says I will be beautiful without one but he also doesn't want me to change for him which is why I still wear it and he is fine with it. Also, I don't sleep with it :p
Sorry for essay. Maybe one day I will get a good pic where you can also see the design and not just a dot :p
Some company in India got an online store where I buy them because the store at the mall closed down. It was ok tho because the online store got more option and a package is only 29 cents so it's great :p Also they are stickies, not piercings. Its funny how everyone I meet randomly out in public think its a piercing 99.9% of the time.
