Handmade with bugle beads and Swarovski crystal accents. This is a new original design with a different look for the Essential Oil Diffuser necklace. The oil receptor is a wool pompom that can be refilled over and over with the oil of your choosing. This design comes on a gold chain, but the diffuser would also look great by removing the chain and adding a string and hanging it in your car as a car freshener. The heat of your car will emit the smell and reflect the magnificent colors of the Swarovski crystals.
