Check out these wedding bands by Sakurako Shimizu. They are molded into a waveform representation of your partner's voice recorded saying "I do," or any phrase you choose. A very cool and unorthodox idea!
This is the professional photo taken of my custom designed engagement ring! It was designed after the Zora's Sapphire from Legend of Zelda: Ocarina of Time! My fiancé and I are huge Zelda fans, and of course, our wedding planning is already Zelda-theme centered! He proposed to me on May 29, 2011 while we were on vacation!
