SOME LIGHT TARNISH below description meaning of the pendant I found on line: In ancient Indian and Persian tales Onyx is referred to as a protector from evil. The Indian gemologists describe onyx as a protector for harmonious relationships. The stones' close union and yet strong contrast between the layers of black and white are considered symbolizing for the love between two people. Black onyx has a calming quality, which can be beneficial in working with challenging emotions such as grief and anxiety. Black onyx also helps to balance yin and yang. It helps us to feel centered, make wise decisions, and get to the root cause of issues.
