Men Silver Ring, Black Onyx Ring, Oval Gemstone Ring, Sterling Silver Ring, Black Zircon Stone Ring on the Band, Mens Jewelry, Husband Gifts I love to use black onyx gemstone with my sterling silver men's handmade rings. Why? As a result of researches, it has been determined that onyx, which is one of the strongest natural stones in terms of its properties, provides balance in male and female relations. Aiding in positive thinking, onyx is effective against stress and depression. Known as the lucky stone, this stone gives a person happiness and increases self-confidence. This 925 sterling silver ring, designed with onyx stone, which is also effective against the evil eye, weighs approximately 17 gr, and I designed it in this way to resemble the walls built by stone masters.
