The Benevolent Postcard Society: Postable JewelryNot only does London-based jewelry designer Nutre Arayavanish create beautiful modern pieces that last forever, but she also has a more ephemeral and conceptual line too — Postable Jewelry. Made of wood, the postcards that can be sent through the mail — the happy recipients can then pop out the pieces and make them into playful and imaginative rings.
