Great Hamsa Charm Stainless Steel Ring.

The khamsa (Arabic: خمسة ‎, Hebrew: חמסה‎, khamsa lit. five, also romanized hamsa and chamsa) is a palm-shaped amulet popular throughout the Middle East and North Africa.[1] The khamsa is often incorporated in jewelry and wall hangings, as a superstitious defense against the evil eye.[2] It is believed to originate in ancient practices associated with the Sabaeans and Nabataeans.

There are two main styles of a hamsa hand: the stylized hamsa hand with two symmetrical thumbs, and hamsa hands that are not symmetrical and shaped like actual hands.[11] Either hamsa hand can be worn with the fingers pointing up or down. The hamsa is popular as a charm most often worn as a necklace, but can be found as a decorative element in houses, on key chains, on other jewellery items.[1] Many artists use the image of the hamsa hand in jewelry, paintings, sculptures, wall decorations, and amulets. The renewed interest in Kabbalah and mystical Judaism is a factoring in bringing the hamsa pendant back into vogue. In Jewish mysticism, fish are a symbol of good luck, so many hamsas are also decorated with fish images. Sometimes hamsas are inscribed with Hebrew prayers, such as the Sh'ma, Birkat HaBayit (Blessing for the Home), or Tefilat HaDerech (Traveler's Prayer).
