Onyx glasses chain, finished in silver. The meaning of onyx is health and warding off evil. The other natural stone used, goldstone, means fortune. Silver hematite, which is non-magnetic, is also used. Its meaning is health. All are made of natural stones, not beads. The price is a bit high, but they are natural stones. Thank you for your understanding. The length can be changed from silver to gold, and other natural stones such as magnetic hematite can also be changed. Please feel free to contact us. Thank you for visiting. We will be open during the Obon holiday. Thank you.
