Alaia Koa Earrings. (pronounced [aːˈlɐjaː]) Our ancestors invented surfing. They rode these round-nosed, square-tailed surfboards. The boards were between 7 and 12 ft (2.1 and 3.7 m) long, weighed up to 100 lb (45 kg), and were generally made from the wood of Acacia koa. We honor those who braved the surf without a leash and offer our rendition in this earring.
