"And you,Frodo Baggins, I give you the light of Earendil, our most beloved star. May it be a light for you in dark places, when all other lights go out." - Galadriel
Salt pendants contain a salt crystal, wrapped in silver or copper wire. The salt crystal feels like a rough and otherwise unremarkable rock, but when you wear one, you will know it as anything but unremarkable.
As said, salt crystal stores and releases water. This produces negative ions. We do not know for certain if body heat warms the crystal sufficiently to do this, however wearing the crystal does seem to promote a sense of clarity and balance. The crystal becomes quickly attuned to the essence of its wearer, probably from absorbing water. It seems to give a life-sustaining boost. Plus, it hangs over the thynus gland, of fourth chakra. This also helps the body become balanced through compassion.
The salt crystal has a silver or copper wire wrapped around it, each individually done to fit the contours of the crystal. Note: the pendant does not come with a chain.
