Sterling Silver Bee Charm on Yellow Glass Essential Oil Diffuser Necklace, #6565 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! (My daughter has been wearing hers to school with her favorite oil.) Our glass necklaces hold 2-3 drops of essential oil. The cap has a hole in it, so while you're wearing you'll get soft hints of the scent. You can also lift the pendant up to your face and inhale the scent. 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. We paired this yellow aromatherapy necklace with a tiny sterling silver honeybee charm. To view more options, 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, sterling silver bee charm
