New necklace

So I just ordered a necklace. I realize that I probably shouldn't but I couldn't contain my urge to be a super nerd. Incase you dont know me personally I am currently working on my masters degree in chemistry. Currently one of the classes I am taking is Molecular Spectrscopy and well this necklace looked like some of the wave patterns we were learning about in class last week.
I found my little treasure on Etsy.com and the link to the seller is, http://www.etsy.com/shop.php?user_id=5671182

I bought the green rectangular version of this necklace but here is a good idea of her work!
