History of Howlite Stone

Discovered by Henry How (1828–1879) in 1868, howlite stone is a semi-precious stone that was found in a gypsum quarry near Windsor, Canada. During drilling and extraction, the miners reported this unknown stone to chemist, mineralogist and geologist Henry How. This natural stone is best known for its resemblance to other types of stones, including turquoise stone.

First named silico-boro-calcite in 1868, mineralogist and geologist James Dwight Dana (1813–1895) christened it howlite stone in honour of Henry How. American Indians use howlite stone as a shamanic stone during rituals, and as a healing stone. They wear howlite pendants at the solar plexus as a protective amulet. The American Indians named it ‘white bison stone’ and ‘sacred bison stone’ as it is considered as rare as white bison in South America.

Origin and Composition of Howlite Stone

Howlite stone is a calcium silico-borate and belongs to the calcite group. This fine and semi-precious stone can be found translucent but also opaque, varying in shades between light yellow, white and light green. It can sometimes have a porcelain aspect. Howlite is a porous stone and is unfortunately used to replicate other stones and minerals through dying (such as turquoise when tinted blue or lapis lazuli when tinted red). Howlite stone is widely used to make decorative objects and jewelry such as howlite necklaces or howlite bracelets.

The main deposits of howlite stone are located in Germany, Austria, Brazil, Canada, the United States, France and Italy. Often likened to magnetite, it is possible to find it under the names: howelite, khaulite, silicoborocalcite, turquenite, white turquoise and winkworthite.
