Brown symbolizes: earth, order and convention. Brown can mix into many surroundings. It is a mixture of red, blue and yellow and has many shades and tones - each producing a different effect. Brown can be a stabilizing color.
The red in brown gives it practical energy while the yellow and blue add mental focus energies. Too much brown can make a dull effect. Brown gives a feeling of solidity, and allows one to stay in the background, unnoticed. Some shades of brown create a warm, comfortable feeling of wholesomeness, naturalness and dependability.
Brown gemstones act as a grounding force and promote stability and clear thinking.
