So let’s talk about what material do I use in the jewelry to hold the oil? ⠀ Porous black lava rock that have been shaped in to beads by a professional. ⠀ Why?⠀ They have pores, these pores in the stone allow the essential oil to be absorbed and sit within the stone, so the wearer can enjoy aromatic benefits of their favorite essential oil. ⠀ .⠀ How long does it last?⠀ It can last up to 1-3 days depending on the scent. Some scents are stronger than others (ie; cinnamon blends, peppermint blends ect) hence they last longer but let’s say lavender, it last about 2 days.⠀ .⠀ Can you switch oils?⠀ Yes ma’am, Carrier oils!! Using a carrier oil apply it to the stone, let it sit wipe throughly with a clean dry cloth, then apply new essential oil. Don’t wash your necklace or bracelet, it will unfortunately tarnish other components and water and oil don’t mix so it won’t fully take away the scent.
