This diffuser necklace is simple, affordable, and one of my favorite quick DIY projects. You can make your own for about $1–$2 each, depending on the materials you choose. They’re perfect for craft classes, party favors, team gifts, teacher appreciation, or a handmade treat to keep for yourself.
These necklaces are incredibly quick to assemble — I made 20 in around 15 minutes. No special tools or jewelry experience required, just a few basic supplies and a few drops of your favorite essential oil.
Supplies

Silver plated metal bead cage pendants — a small, decorative wire cage pendant that holds a lava bead or felt ball.

24″ silver plated snake chains — smooth metal chains that slide easily through the pendant loop.

Waxed cotton cord necklaces — an inexpensive, colorful alternative to metal chains for a more casual look.

Lava beads — porous volcanic stone beads that hold and diffuse essential oils for hours.

Colorful lava beads — same porous texture but available in bright colors to match your style.

14mm wool felt balls — an attractive and fragrant-friendly option to use inside the cage pendant instead of lava beads.

Step-by-Step Instructions (as easy as 1-2-3)
Putting these diffuser necklaces together takes only a few simple steps. No tools are needed for the basic version.
1. Pop a lava bead or wool ball into the wire cage
Gently pry the cage open with your fingers just enough to slide the bead or felt ball inside. The cage snaps back into place and secures the bead without glue or clasps.



2. Slide the chain or cord through the pendant
Run your chosen chain or waxed cord through the pendant’s bail and fasten the necklace. That’s all there is to the assembly.

3. Add essential oil and enjoy
Place a few drops of your favorite essential oil directly onto the lava bead or wool ball inside the cage. Reapply every few days or when the scent fades. The porous bead holds the oil and slowly releases its aroma throughout the day.
