What is howlite? (Calcium Borosilicate Mineral)
Howlite is a rare calcium borosilicate mineral with the chemical formula Ca₂B₅SiO₉(OH)₅. Its structure is generally lumpy and opaque, and it stands out with irregular gray or black vein patterns on a white background. These veins are matrix remnants of the stone.
Mohs: 3.5 • Density: ~2.6 g/cm³ • Formula: Ca₂B₅SiO₉(OH)₅
The main components of the mineral are boron and silicon. Despite its low Mohs hardness (3.5), it is often dyed to imitate harder and more colorful stones such as turquoise or lapis lazuli due to its porous structure, but even in its natural form it has a strong energy.
Formation & Resources
- Geological Formation: It is generally found in evaporite deposits and sedimentary rocks where borate minerals are formed.
- Major Sources: Canada (Nova Scotia), USA (California), Mexico and Germany.
- Appearance: Thin, dark gray or black veins intersected by matrix inclusions in white or gray tones.
History and Meaning (Henry How Discovery)
Howlite is named after Canadian chemist, mineralogist and geologist Henry How, who discovered this mineral in Nova Scotia, Canada, in 1868. Although originally named Silicoborocalcite, it was later formalized as Howlite in How's honor.
Howlit is a key to achieving mental silence; It opens the door to wisdom and spiritual journey.
Its Place in Cultures and Astrology
- Symbolic Meaning: Patience, serenity, anger management and mental purification.
- Usage: It is popular to place it under the pillow to improve sleep quality, especially during stressful periods.
- Astrology: It is associated with the zodiac signs Aries and Gemini. While it calms Aries' sudden anger, it slows down Gemini's excessive thoughts.
Physical and Chemical Properties (Mineralogical Analysis)
Howlite is characterized by its softness and porous structure. These properties make it both a valuable accessory and a mineral that requires careful care.
Crystal System
Monoclinic. It occurs as prismatic or tabular crystals, but most often occurs as clumped nodules.
Chemical Structure
Calcium Borosilicate. Its chemical formula is Ca₂B₅SiO₉(OH)₅, and boron and silicon have an important place in its composition.
Hardness (Mohs)
Very low: 3.5 Easily scratched with fingernail or iron nail; This makes it a delicate stone for jewelry making.
Specific Gravity/Density
It is in the range of 2.53-2.59 g/cm³. The average is considered to be 2.58. This makes it a porous and relatively light mineral.
Brightness and Appearance
It has a matte and porcelain (sub-vitreous) shine. It shows a transparency varying between opaque and translucent.
Refractive Index
n ≈ 1.586–1.605. This value is slightly higher than glass and refracts light moderately.
Cleavage and Fracture
Its cleavage is not obvious. The fracture type is conchoidal (like a mussel shell) and irregular.
Line Color
The powdered color of the mineral is the same as the ground color: white.
Common Imitation
Due to their porous structure, the minerals most frequently imitated by painting are: Turquoise and Lapis Lazuli.

Howlite Quality Assessment and Maintenance Guide
Howlite requires special care due to its natural structure.
Color Originality
Natural Howlite is white. Stones may be dyed intense blue (imitation of Turquoise) or other colors.
Surface Fineness
There may be natural small gaps or irregularities on the surface. Very smooth and smooth surfaces may indicate a synthetic or artificial product.
Sensibility
The fact that it can be easily scratched with a fingernail or needle (Mohs 3.5) is indicative of true Howlite (though scratching your stone is not recommended).
Maintenance and Cleaning
It has a porous structure that can absorb water. Therefore, it should not be immersed in water for a long time.
Keep Away From Chemicals
Chemicals such as soap, detergent or acid can discolor or damage its structure due to its porous structure.
Energy Cleansing
Incense smoke or full moon light is recommended for energy clearing.

Frequently Asked Questions
Is Howlite a substitute for Turquoise or Lapis Lazuli?
Howlite is dyed and imitates the appearance of these stones, but its chemical structure and energy are completely different. Dyed Howlites are often sold as imitations of Turquoise.
What is the difference between Howlite and Magnesite?
Both stones are white and may have similar vein structure. However, Howlite is a borosilicate while Magnesite is a magnesium carbonate (MgCO₃). Magnesite is slightly harder than Howlite (Mohs 4-4.5).
What is the effect of Howlit on anger management?
According to traditional belief, Howlite has the power to absorb tension and slow down overreactions. It is recommended to hold it in the palm of your hand in a moment of anger.
