Posts and clutches on all post earrings are made of solid sterling silver. Cloisonné 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. Lastly, all Bamboo Jewelry comes packaged in eco-friendly bamboo gift boxes lined with anti-tarnish fabric.
