Howlite and Purple Amethyst Druzy

Physical Properties

Howlite: Hardness 3.5, white with grey veins, sub-vitreous to earthy luster, monoclinic. Amethyst Druzy: Hardness 7, purple, vitreous luster, hexagonal crystal system.

Formation & Geological History

Howlite is an evaporite mineral found in nodules. Amethyst forms in geodes within volcanic rock. Purple druzy is often color-enhanced or treated quartz to achieve deep saturation.

Uses & Applications

Used primarily for costume jewelry, beads, cabochons, and decorative carvings; popular in metaphysical and crystal healing communities.

Geological Facts

Howlite is naturally white/grey but is the most commonly dyed stone in the market, often used to imitate turquoise or lapis lazuli due to its porous nature.

Field Identification & Locations

Identify howlite by its erratic grey 'spider web' veining. Identify druzy by its sparkling, sandpaper-like surface of tiny crystals. Found commonly in California (USA) and Nova Scotia (Canada).
