Elastic mala/bracelet with 21 beads of amethyst, with ohm symbol.

Amethyst has a spiritual quality that can be used to help tap into higher levels of consciousness. It can serve as a bridge between the physical and ethereal realms.

Mala 
A mala originally is a hinduistic and buddhist tool for prayer and meditation. It is used to count mantras during meditation. A mantra is a collection of words, often from Sanskrit, which is repeated several - traditionally 108 - times. While repeating, you focus on the meaning and vibration of the words, possibly combined with the accompanying visualisation. By training in a meditation practice like this, your thoughts come to rest and your body relaxes.
