Bat and Moon Necklace by BambooSolid sterling silver chains adjustable from 16"-20", so they fit almost anyone. Necklace clasps are made of sterling silver, and the six small crystals on small necklaces are genuine Swarovski crystals. Cloisonne jewelry is handcrafted by fusing kiln-fired glass to a sterling silver foundation, and each color is outlined by a fine braid of silver wire. All Bamboo Jewelry is enameled on both the front and back which strengthens pieces and makes the backside smoother to the touch. Bamboo Jewelry comes packaged in eco-friendly bamboo gift boxes lined with anti-tarnish fabric.
