The boldest accessories celebrities wore this week

With just one statement necklace, an everyday outfit like a black T-shirt and jeans can go from boring to effortlessly bold. It might sound insanely simple, and believe it or not, it can be, as celebrities like Bella Thorne, Zoe Saldana and January Jones have demonstrated. While they're often all dolled up on the red carpet from head to toe, they're also the kind of fashionable Hollywood stars who understand the power of a bejeweled hair piece or a stack of sparkling bracelets. If you're looking for style inspiration, follow some pointers from these accessorizing experts.

Zoe Saldana
The former ballerina Zoe Saldana has been promoting her latest film, "Star Trek Into Darkness," all over the world, and has looked amazing while doing it. Her recent ensemble for the film premiere in Berlin, Germany, caused a stir in the fashion realm because of her perfectly tailored gray Calvin Klein dress and bridal-inspired updo, with a jeweled hair accessory that gave it a vintage feel. Saldana's earring choice was simple to keep the attention on the Jennifer Behr Vine Circlet that fit perfectly into her pulled back hairstyle. Topping off the look with bright red lips, Saldana looked like a model rather than a famous actress.

Bella Thorne
At the Radio Disney Music Awards, Bella Thorne looked the part of a bright young star, wearing one of the most eye-catching statement necklaces at the event. The Cameo Jewels Bib Necklace by Kate Spade matched her other fluorescent-colored accessories, including her playful neon bangles and lime green heels, which she wore with a strapless navy dress covered in roses. The 15-year-old Disney star is currently writing a book series, called "Autumn Falls," which will cater to girls her age with the same fun and flirty style.

January Jones
If there's one style maven to watch out for, it's January Jones. The blonde-haired, blue-eyed actress on "Mad Men" looks just as flawless on the red carpet as she does shopping for groceries, and always manages to look polished yet not overly put together. Jones has recently called upon the help of her fashionable jeweler friend to help her look her best, reports fashion blog WhoWhatWear. 

"My favorite jewelry right now is my friend Lori Heuring's line called Ivy Diamond Cole," she told the news source.

After throwing on one of Heuring's cocktail rings, a fitted pair of jeans and some Derek Lam sunglasses, Jones is ready to hit the streets and take on the paparazzi in her perfectly accessorized attire.
