Bryan Adams, whose current Shine A Light Tour ensures one tree is planted per ticket sold, continues to donate his used guitar strings to the charity Wear Your Music. Founder and designer Hannah Garrison makes and sells gorgeous custom jewelry out of them. Fittingly, the pop hitmaker selected Nordoff-Robbins as the recipient of the proceeds. The U.K. music therapy charity “use[s]music to enrich the lives of people with life-limiting illnesses, disabilities and feelings of isolation.” Adams’ strings have been made into bracelets, cuffs and pendants, ranging from $65 to $275 USD. The pendant, for example, features a stainless steel and glass locket on a boxchain necklace. Buy them here. — Karen Bliss
