Since wavellite’s radiating crystal clusters can splinter, they make it a very difficult gem to cut. The individual crystals in the clusters are very small. Gem cutters can fashion cabochons as well as freeform shapes from this material. However, any faceted gems would be a tremendous rarity.

This striking specimen displays massed, acicular, “needle-like,” crystals radiating from the center of the stone. You can also see how one “ball” of wavellite grew around another. “Wavellite,” 3.4 x 2.0 x 1.1 cm, Avant Mine, Avant, Garland Co., Arkansas, USA. © Rob Lavinsky, www.iRocks.com.

Stone Sizes

Lapidaries can cut cabochons up to several inches in length from Arkansas material. No faceted gems have been reported, yet.


Wavellite has a relatively low hardness (3.5 to 4) and perfect cleavage. Thus, jewelry pieces such as rings need protective settings. Pendants and earrings would make excellent choices for this material. However, you’re more likely to encounter these stones in gem collections than jewelry collections.

Store these gems separately from other harder stones to avoid contact scratches. For cleaning, use a soft brush, mild detergent, and warm water. Consult our Gemstone Jewelry Cleaning Guide for more recommendations.
