Howlite

Howlite is a calcium borosilicate mineral, usually found as white or creamy nodules with fine grey or black web-like veining. It was discovered in 1868 near Windsor, Nova Scotia, by the Canadian chemist and geologist Henry How, after whom it is named. Most howlite used in jewellery comes from California, where it is found in borate deposits, as well as from Canada, Turkey, Germany and Mexico.

In its natural state howlite is sold as white beads, cabochons and carvings, sometimes under names such as "white turquoise" or "white buffalo stone", although it is not turquoise. Its veined appearance, together with its porous texture, makes it very easy to dye, and it is widely dyed to imitate other stones. Blue and green dyed howlite is one of the most common imitations of turquoise (sometimes sold as "turquenite"), and it is also dyed to imitate lapis lazuli, coral and other stones, as well as in bright, fashion colours.

Dyed howlite can often be identified by the colour concentrating in cracks and veins, or by a little dye coming off on a cotton bud dipped in acetone. Howlite is soft, so it scratches more easily than turquoise. It is very similar in appearance to magnesite, which is also widely dyed, and the two are often confused.

Caring for howlite

Howlite is soft (3.5 on the Mohs scale) and porous, so it scratches easily and can absorb oils and chemicals. Clean it gently with a soft, damp cloth only. Avoid soaking it, and never use ultrasonic or steam cleaners. Keep it away from perfume, cosmetics and cleaning products, and out of strong sunlight and heat, which can fade dyed howlite. Store it separately in a soft pouch.

In folklore

The beliefs below are traditional folklore, included for interest. They are not scientifically proven, and nothing here is medical advice.

As a mineral first described in 1868, howlite has little ancient folklore. In modern tradition it is associated with peace and patience and is often placed under the pillow to encourage restful sleep. Its white form is sometimes linked with the White Buffalo of Native American legend, which led to the trade name "white buffalo stone", although this name is also used for a different stone. Howlite is associated with the zodiac sign Gemini.

Howlite is traditionally regarded as one of the most calming stones. Crystal healing lore holds that it soothes anxiety, stress and anger, encourages patience and restful sleep, and helps quieten an overactive mind. It is also said to aid memory and the desire for knowledge. It is linked to the crown chakra.
