A protective Hamsa (the hand against the evil eye and bad energies) made of onyx and on whose stone the 72 cabalistic names of God are written in nano script and in the center a Star of David (Maguen David). Powerful I said with the cabalistic names and the Hamsa. To read the nano writing, this fabulous article is accompanied by a magnifying glass and an Italian sterling silver chain box. The chain is sterling silver. Sterling silver is the purest and is made up of 99.9% silver and a small portion of other metals such as copper. Better known for 925. The size of the earring is 12mm x 10mm (:0.5" x 0.4") and the length of the chain is 45cm (18").
