White Hamsa Hand Star of David Spiritual Necklace

Hamsa - the Hamsa Hand, or Hand of Miriam, is one of the original symbols for protection. The hamsa eye-charm is considered to be effective in warding off the influence of envious gazing.
According to the Kabbalah, the two triangles facing opposite directions represent the dichotomies inherent in man: good vs. evil, spiritual vs. physical, etc.
The hamsa or "protecting hand" is believed to be a way of averting and getting protection from the evil eye, or in general, as a way of summoning assistance from the "Hand of G-d".
