It’s always nice when your jewelry makes a statement, but here’s a way you have control over what it actually says.
Bza.biz can craft jewelry in the shape of the sound waves of a recording you send them. They offer a variety of different materials; plywood, black plywood, white, blue or “radiant” acrylic. Even silver.
The plywood and acrylic are discs that are strung in the shape of the sound. Or, if you don’t like that idea, you can have it cast in silver as either earrings or a keychain.
