This mineral
was discovered in Nova Scotia in 1868 by Henry How. Mr. How was a Canadian chemist, geologist and
mineralogist who was told of this previously unknown mineral by gypsum quarry
miners who found it hampered their mining because it is harder than gypsum.
Howlite is
a borate mineral, which occurs in Canada and parts of the USA. It forms as
irregular nodules which can appear in the shape of a cauliflower head.
Transparent howlite crystals are extremely rare and are small (the largest
documented howlite crystals are 1 cm long), but the nodules can occur in masses
of over 50 kilograms.
Howlite
has the appearance of white marble or porcelain with a sub-vitreous lustre. It
is opaque and white or grey with grey, black or dark brown veins running
through it.
Gemstone
quality howlite can be interspersed by the darker matrix (which appears as the
veins), or it can be matrix-free and pure white. Howlite is best known for
imitating other gemstones. Due to its porous nature, howlite can absorb dye
well, which means it can be sold as turquoise, red coral, or lapis lazuli. However,
honest gem traders always declare any treatments.
* This gemstone has been dyed Turquoise.
