The "Daughters" star, who is a keen watch collector, has teamed up with jeweller George Frost to launch the limited edition range, which includes beaded necklaces and hand-woven bracelets, which feature song titles like "Born and Raised", "Wildfire" and "Neon", reported Contactmusic.
Prices start at USD 50, with the most expensive piece - a silver pendant with a revolving charm, which read, "Love is a verb" - retailing at USD 190.
The simple jewellery collection isn't the only new project Mayer has been working on of late. Earlier this month, he announced he had teamed up with bosses at household goods firm The Laundress for his own laundry product line.
