Lavender Glass Essential Oil Diffuser Necklace on Sterling Box Chain, #6619 We have become obsessed with essential oils at the Zoe and Piper office lately! The problem was, there was a lack of jewelry for essential oils. After a lot of research we came up with several options that we're super excited about - and the best part? They're great for children and adults alike! Our cube shaped glass necklaces hold 2-3 drops of essential oil. The cap has a hole in it, so while you're wearing you will get soft hints of the scent. You can also lift the pendant up to your face and inhale the scent, when you need a quick shot of peppermint to stay alert for instance! A solid cap is included with the necklace. This is handy to put on at night so your oil doesn't evaporate as quickly (the oil evaporates after appx. 48 hours with the diffuser cap left on at all times). If you keep the solid lid on, your oil will not evaporate. Choose your pendant color and length of a sterling silver box chain, or add a small sterling silver charm to your necklace! We offer a lotus flower, om symbol and dove already made up, or add a charm of your choice! This listing is for a lavender necklace, see our diffuser necklace collection for a full selection of styles. You can use any essential oil or perfume of your choice. Each necklace ships with a pipette for easy refilling and an essential oil sample. Size: Vial is appx. 3/8" x 7/8", Material: glass, sterling silver box chain, base metal lid, sterling silver jump ring
