Color: White body with red-dyed veins; Streak: White; Cleavage: None visible in massive form; Fracture: Subconchoidal to uneven; Specific Gravity: 2.53 - 2.59; Fluorescence: Often fluoresces brownish-yellow or white under Shortwave UV.
Optical Properties
Refractive Index: 1.583 - 1.605; Birefringence: 0.022; Optically Biaxial (-); Opaque in massive form; shows no pleochroism or dispersion.
Hardness & Durability
Origin Region
Primarily Tick Canyon, California, USA; Nova Scotia, Canada. Dyed varieties are processed globally for the jewelry trade.
Hardness & Durability
Mohs hardness: 3.5. It is relatively soft and brittle, making it susceptible to scratches and damage from impact.
Care & Maintenance
Clean only with warm soapy water and a soft cloth; avoid ultrasonic cleaners, steam, and harsh chemicals. The dye may fade if exposed to prolonged direct sunlight or chemical solvents.
Rarity & Value
Very Common; Howlite is an inexpensive mineral frequently used as a simulant for pricier stones like turquoise or coral when dyed. Value is primarily in the carving craftsmanship.
Special Characteristics
This specimen is notable for its 'Spider-web' veining, which is a natural feature of howlite that has been artificially enhanced with red pigment to mimic cinnabar or red jasper matrix.
Lore & History
First discovered in 1868 by Henry How. Historically used as a decorative stone. In metaphysical traditions, it is associated with the Root Chakra (when dyed red) and is believed to aid in patience and calming anger, though these are not scientific claims.
