Sierra Sonoma Designs are created in the studio of Sonoma Art Works, located in Sonoma Valley amidst the vineyards of northern California's wine country. The jewelry is designed by the artist Cheryl Sirkus whose designs begin on her sketch pad and are transformed into the precious metals, gemstones and crystals that are used. Most of the original designs have been hand cast in sterling silver and 14k gold vermeil. They capture the feeling of understated elegance and femininity.
