This necklace has a solid sterling silver chain adjustable from 16”–20”. Necklace clasps are made of sterling silver, and the six small crystals on small necklaces are genuine Swarovski crystals. 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. It is enameled on both the front and back which strengthens pieces and makes the backside smoother to the touch. and comes packaged in eco-friendly bamboo gift boxes lined with anti-tarnish fabric.
