TMZ's hungry paps caught a glimpse of Justin Bieber's new icey investment. Is Biebs taking a cue from Gucci Mane?

"Famous Beverly Hills jeweler Jason Arasheben tells TMZ, he and Bieber designed the Stewie pendant together -- adding, Justin "had a specific vision for how he wanted it to look."

Jason tells us, the necklace contains 12 carats of precious stones -- including multi-colored rubies and white diamonds -- and they're all set on 14-carat gold."
