The beads in a chakra bracelet can be made of many materials, but the colors are very important. Each of the chakras is represented by a color — violet/white, indigo, light blues, green/pinks, yellows, orange, and reds.
The only essential feature of a chakra bracelet is that its wearer understands its significance. Not every rainbow colored bracelet is a chakra bracelet, but all bracelets colored this way can be worn as chakra bracelets and thereby achieve the intended balancing and healing effects.
About Lava Rocks: Basalt and related rock types like andesite and dacite are rocks that form when volcanoes erupt magma (lava) onto the surface of the earth and the magma cools. Lava beads are porous and can absorb the oil of your choice.
Directions: I suggest applying just a drop or two of essential oil to the beads. The scent will last a day if not more. You can use any of your favorite essential oils. The rocks are mounted on a sturdy plastic stretch cord to minimize extra weight on your arm since the rocks themselves are fairly dense to be a jewelry item.
