What is howlite?

Howlite: A Calming and Versatile Mineral

Howlite is a borate mineral typically found in evaporite deposits. It is named after Henry How, a Canadian chemist, geologist, and mineralogist who first discovered it in Nova Scotia in 1868.

Key Characteristics:

• Appearance: Howlite is usually white or light gray with fine, irregular veins of gray, dark brown, or black. It can also be found in a nodular form.
• Composition: It's a calcium borosilicate hydroxide with the chemical formula Ca₂B₅SiO₉(OH)₅.
• Hardness: Howlite has a relatively low hardness of 3.5 on the Mohs scale, making it easily carved and shaped.
• Luster: It exhibits a dull, subvitreous luster.
• Transparency: Howlite is opaque.

Uses:

• Ornamental Stone: Due to its porous nature and ability to take dye readily, howlite is frequently dyed to imitate other minerals, particularly turquoise and magnesite. It is used in beads, carvings, and other decorative objects.
• Metaphysical Properties: In metaphysics, howlite is believed to be a calming stone that can help reduce stress, anxiety, and anger. It is also thought to promote patience and clear communication. Some believe it aids in restful sleep and can be beneficial for insomnia.
• Industrial Applications: While less common than its ornamental use, howlite's boron content makes it potentially useful as a source of boron.

Occurrence:

Howlite is found in various locations worldwide, including:

• Canada (Nova Scotia)
• United States (California)
• Germany
• Turkey
• Mexico

Note: While often sold as turquoise, genuine turquoise is significantly more valuable and has a different composition and geological formation. It is essential to be aware of this when purchasing howlite, especially if you are specifically seeking turquoise.
