Wire cages offer flexible jewelry solutions for crystals and stones. These spiral wire cages are perfect for carrying your stones around, keeping their energy within your aura as you go about your day. Each cage has a loop on top big enough to thread any chain, ribbon, or thong, and they will stretch to accommodate crystals that are up to 1.5-times the unstretched size of the cage. The smallest cages are fantastic for chips! Plus, the ability to swap out your crystals as needed gives your necklace, bracelet, or keychain the flexibility of using a variety of stones at different times. These wire cages come in two colors, gold and silver, and 3 sizes. They are made of plated alloy. Sizes include the top loop in measurement.
