Quick Facts
Formation & Origin
Wavellite forms as a secondary phosphate mineral in low-temperature hydrothermal environments, often in fractures within aluminous, phosphatic rocks. It's particularly common in areas where phosphate-rich groundwater interacts with aluminum-bearing rocks.
The most distinctive feature is its radial crystal habit. Wavellite grows in spherical aggregates where needle-like crystals radiate outward from a central point like starburst fireworks. When these spheres are cut in cross-section, they reveal the beautiful radial pattern that makes wavellite one of the most visually striking of all minerals.
Arkansas produces the world's finest wavellite from the Ouachita Mountains region, where phosphate-rich solutions percolated through Paleozoic sedimentary rocks. The green color comes from trace amounts of iron and vanadium.
Identification Guide
Wavellite's radial, starburst growth pattern is diagnostic. When hemispheres are broken or cut, the concentric and radiating structure is unmistakable. Green to yellow-green color, relatively low hardness (3.5), and association with phosphatic rocks are additional identifiers.
Distinguish from variscite (massive, lacks radial habit), malachite (botryoidal rather than radial, contains copper), and prehnite (different crystal system and habit). The radiating crystal pattern in cross-section is the most reliable identification feature.
Spotting Fakes
Wavellite is not commonly faked. The radial crystal structure is too complex and distinctive to replicate easily. The main issue is quality and provenance. The finest specimens from Arkansas show vivid green color with well-defined radial patterns. Less impressive specimens may be pale or have poorly defined radiating structures. Sellers sometimes enhance green color, so very vivid specimens should be examined carefully.
Cultural & Metaphysical Traditions
Presented as cultural traditions, not scientific evidence
Wavellite's radial growth pattern has made it a symbol of expanding awareness and seeing the big picture in crystal healing. Practitioners use it for gaining perspective on complex situations, understanding interconnections, and overcoming tunnel vision. The starburst pattern is sometimes used as a focus for meditation on radiating positive energy outward.

Good to Know
Scratch test: At hardness 3.5, Wavellite can be scratched with a copper coin. Handle gently and keep away from harder stones in your collection.
Sources: Found in 4 notable locations worldwide, from United States to Australia.
Heft test: With a specific gravity of 2.36, Wavellite feels lighter than most minerals. This lightness can help identify it.
