So you are looking for some nice piece of jewelry for your loved one, who is a music freak like you? Look no further! Sakurako Shimizu's Waveform Jewelry Series is just for you. All these rings, earrings and necklaces are laser-cut shapes of the waveforms, he uses some human sound such as yawn, atchoum, giggle, wow, and the sound of church bell. But I'm sure the best motive would be the waveform of your lates track, hehehe.
