Jade

Birthstone for Aries, Gemini, Taurus and Libra
Chakra alignment depends on colour
Properties: Jade comes in 6 different colours: yellow, red, black, green, white and purple. It has been considered a "good luck" stone for thousands of years, and has been treasured by the Chinese since at least 1950 BC. Ancient cultures in the Americas and Asia used it as a kidney healing stone. The Chinese use it to strengthen the body, increase longevity and cleanse the blood, and consider it a symbol of purity and wisdom gathered in tranquillity. It encourages self-realisation, particularly on a spiritual level, and is very balancing. It is also used in dream work.
