Howlite is a borate mineral found in evaporate deposits. It was first discovered in Nova Scotia in 1868 by Henry How when miners in a gypsum quarry found it to be a nuisance. It is a whitish-gray colour with gray veins in a web-like pattern. Howlite is often dyed to resemble other stones such as turquoise or chrysocolla.
As a healing stone howlite is calming; used to relieve tension and anxiety. Place a piece of howlite under your pillow to fight insomnia.
