What is howlite?

Howlite is a borate mineral, typically found in evaporite deposits. Here are some key details about howlite:

1. Chemical Composition: Howlite is composed primarily of calcium borosilicate hydroxide, with the chemical formula Ca₂B₅SiO₉(OH)₅.

2. Appearance: It typically appears as white or gray, with veining that ranges from black to gray, which can resemble marble or porcelain. This veining is quite distinctive and can give howlite its characteristic appearance.

3. Crystal Structure: The mineral forms in nodules resembling cauliflower heads, but it can also be found in crystalline form, where it appears as small, white monoclinic crystals.

4. Hardness and Durability: On the Mohs scale of mineral hardness, howlite ranks at about 3.5, making it relatively soft compared to other minerals. This low hardness makes it easy to carve and shape, which is why it is often used for decorative purposes.

5. Uses: Howlite is often used as an ornamental stone and is sometimes dyed to mimic turquoise or other gemstones due to its porous nature. Its ability to be dyed various colors makes it popular in jewelry making. It is also commonly used as a decorative stone in carvings and cabochons.

6. Location: Howlite was first discovered in 1868 in Nova Scotia, Canada by the geologist and chemist Henry How, after whom it was named. Today, large deposits of howlite can also be found in California, USA.

7. Metaphysical Properties: In the realm of crystal healing, howlite is believed to have calming properties. It is often used for meditation and stress relief, and is thought to help with relaxation and restful sleep. Some also believe howlite can help enhance memory and facilitate emotional expression.

8. Care: Due to its softness and porosity, howlite should be handled with care to avoid scratches or damage. It’s best to clean howlite jewelry with a soft, dry cloth, and keep it away from harsh chemicals and extreme temperatures.

Overall, howlite is appreciated not only for its aesthetic qualities but also for its versatility in jewelry and its perceived metaphysical benefits.
