Handcrafted with lampwork glass by local artisans between Barcelona and the UK. Hoops: 18K gold plated nickel free hoops. 3mm thick and 16mm outer diameter. Bead size: 14mm diameter SOLD AS SINGLE earring. Please add x2 to cart for the pair. The Zero Waste Collection is a sustainable jewellery option. The concept was curated after our glassmakers found they had multiple coloured glass rods left over which were too short to create new beads. We had the idea to break them and incorporate them into a new design to eliminate and use up the "waste", creating the Zero Waste Collection.
