Overview

n

Howlite is a hydrated calcium borosilicate mineral (chemical formula Ca₂B(BO₃)₂·5H₂O) that typically appears white with grey‑blue veining. It is relatively soft (Mohs 3.5), making it easy to carve and dress. Because of its porous nature, natural howlite is often dyed to imitate turquoise or other blue stones.

n

History and Origin

n

Discovered in 1868 in the copper mines of Arizona, USA, howlite was named after Canadian chemist Henry How. Early uses focused on ornamental carving and as a decorative stone. Commercial mining expanded in the early 20th century, especially in Arizona, Nevada, and later in British Columbia, Canada. Today, most high‑quality material comes from the United States and Canada, with smaller deposits reported in Mexico and Turkey.

n

Meaning and Symbolism

n

In traditional gemstone lore, howlite is said to promote calmness, patience, and emotional balance. It is often presented as a stone that encourages inner peace and helps the wearer release anger or stress. The white base is interpreted as purity, while the veining symbolizes the flow of thoughts and feelings.

n

Healing and Metaphysical Properties

n

Crystal‑healing practitioners attribute the following properties to howlite, describing them as traditional beliefs rather than medical facts:

n

n
• Emotional soothing: Helps calm anxiety, insomnia, and emotional turbulence.

n

• Communication aid: Encourages honest expression and reduces aggression.

n

• Spiritual grounding: Supports meditation by quieting the mind, often linked to the Crown or Third Eye chakras.

n

n

These claims are based on long‑standing metaphysical traditions and are not supported by scientific research.

n

Varieties and Types

n

Natural howlite is opaque white with grey‑blue or brown veining. The most common treatments include:

n

n
• Dyed howlite: Typically blue or green to mimic turquoise; the dye penetrates the porous structure.

n

• Polished cabochons: Used in jewelry where the surface is lapped smooth.

n

• Carved beads and figurines: Exploits its easy workability.

n

n

Jewelry Uses and Care

n

Because of its softness, howlite is best suited for earrings, pendants, brooches, and beaded necklaces where abrasion is minimal. It should not be used in rings or bracelets that endure heavy wear.

n

Care recommendations:

n

n
• Clean with warm, soapy water and a soft brush; avoid ultrasonic cleaners.

li>Dry thoroughly; moisture can affect dyed specimens.

li>Store separately from harder gemstones to prevent scratches.

n

• Avoid exposure to harsh chemicals, acids, or prolonged sunlight, which may fade dyes.

Buying Guide

n

When purchasing howlite, consider the following factors:

n

n
1. Origin and treatment disclosure: Reputable sellers will indicate whether the stone is natural or dyed.

n

2. Color uniformity: Natural white with subtle veining is typical; overly bright blue may indicate heavy dyeing.

n

3. Cut and polish quality: Look for smooth, even surfaces without visible pits.

n

4. Certification: For larger pieces, a gemological report (e.g., GIA) can confirm authenticity.

n

n

Because howlite is abundant, price is generally modest, but rare, high‑clarity, naturally veined specimens can command higher values.
