Pennyroyal® Jewelry is a Hermosa Beach design studio, specializing in officially licensed, handcrafted sterling silver accessories for men and women.  

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

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

In addition to capsule 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 created a second branch of the compay called waxoffdesign®, creating premium quality officially licensed, custom collectibles like pins, keychains, bottle openers and much more..  Visit to learn more.
