Pennyroyal® Jewelry is a Hermosa Beach design studio, specializing in handcrafted jewelry and accessories for men and women.  

Pennyroyal® was founded in 2006 when designer, Tim Foster, hammered a penny into a crude shape to make a simple necklace for his girlfriend.  For the following year, Tim studied various jewelry design techniques and released his first collection of sterling silver necklaces inspired by his previous career in the music industry and newly found passion for metalwork and organic textures. 

Pennyroyal® has released over a dozen capsule collections inspired by a wide variety of interests including music, miniature sculpture, the Sierra Nevada mountains, the ocean, space, the Fibonacci sequence and more.

In addition to regular collection releases, Tim’s passion for music and philanthropy gave rise to an ongoing series of design collaborations with a variety of musicians.   Charitable contributions from these releases have raised over $350,000 to date for causes such as MusiCares, Trevor Project, Donors Choose, Jewel's Project Clean Water, The Cesar Millan Foundation, Autism Speaks... and many more.  

In 2016, Pennyroyal Studio, LLC launched a product design company called waxoffdesign®, creating premium quality custom collectibles like pins, keychains, bottle openers and much more..  Visit to learn more.
