Amazonite
Amazonite is a powerful protector against negative energy and electromagnetic radiation. It brings balance between the mind and intuitive wisdom.

Mala
A mala is originally a prayer bead from Hinduism and Buddhism and is used in meditation to count mantras. A mantra is a collection of words, often from Sanskrit, that is repeated several times—traditionally 108 times. This involves focusing on the meaning and vibration of the words, perhaps combined with the corresponding visualization. By practicing a meditation exercise like this, your mind becomes calm and your body relaxes. Nowadays, a mala is also worn as a fashion accessory.
