Howlite
Howlite is cream or white with fine grey or black veins. It resonates with the root and crown chakras. It's said to be calming and can help its wearer to reduce their own levels of stress and anger, as well as anger that is directed towards them. Howlite absorbs negative energy and its calming qualities are thought to also help reduce insomnia as it relieves and unburdens an overactive mind.
