Core Features
zebrawood
Exotic wood with character. Zebrawood is a unique and incredibly beautiful type of wood. It owes its name to the special striped pattern that turns our accessories into extravagant eye-catchers. The fine, high-quality wood is obtained from Microberlinia trees and comes mainly from tropical rainforests in West Africa or Asia.
Perfect for Sets
Birds of a feather flock together. Combine this product with other colors from this collection or necklaces, bracelets, rings or earrings in the same design. Discover all the unique pieces in this collection and complete your one-of-a-kind jewelry set!
