Earth Treasures: Wavellite

By Chisom Ibemere

Wavellite, an Aluminum basic phosphate mineral, was first discovered in the year 1805 in the county of Devon, United Kingdom.

It was named after English physician and mineral collector, William Wavell, who made great contribution to the study of the mineral. It is a phosphate mineral.

Wavellite usually occur in environments where phosphate minerals form, such as in the granite pegmatites, phosphate-rich soils, and hydrothermal veins respectively.

It is primarily found in countries including the United States Germany, France, Brazil, and India.

Wavellite is mainly used as a collector’s gemstone due to its unique spherical crystal clusters, which can exhibit a variety of colors, including green, yellow, and white.

Its aesthetic appeal makes it a popular choice for lapidary arts, where it is cut and polished into cabochons and beads for use in jewelry, decorative objects, and sculptures.

In addition, Wavellite is often used for scientific research as a mineral specimen.

Wavellite is a hydrated aluminum phosphate mineral which typically occurs as radial or spherical clusters of small crystals, giving it a unique appearance.

Itd color can range from light green to yellowish-green or even white, sometimes displaying chatoyancy or iridescence. It has a dull to pearly luster and a Mohs hardness of 3.5 to 4, making it relatively soft compared to other gemstones.

Wavellite is not as popular or widely known or commercially valuable as some other gemstones due to its limited occurrence and specific aesthetic appeal. Its value is mainly driven by its unique crystal formations and color variations.

The value of Wavellite is relatively niche, and its rarity can contribute to its desirability and collectibility among gemstone enthusiasts.

Generally, its global value is not as significant as popular gemstones like diamonds or rubies.
