A wonderful way to turn your crystal tumblestones or small rough crystals into a pendant. This silver-plated metal spiral holder expands to accommodate crystals up to about 3.5cm by about 2cm. It can then be hung on a leather thong or a chain or even added to a keychain to make a keyring. This is an inexpensive way to wear your crystals and to get the energy of the crystal into your auric field.
