Fascinating Facts about Howlite

Howlite is perhaps best known for being an imitation gemstone, as it can be dyed different colors to look like semi-precious gemstones such as Turquoise and Coral. Even though Howlite is generally inexpensive, it still has plenty of qualities that make it a popular stone for use in jewelry-making.

Howlite composition and history

Howlite is a borate mineral found in sedimentary rock. It was first discovered in Canada in 1868 by Henry How, a Canadian chemist, mineralogist and geologist. A group of miners brought it to his attention when they came across it while mining, finding it to be a nuisance because it was harder to mine than gypsum.

Henry How named the mineral “silico-boro-calcite”, but later it was given the name Howlite by James Dwight Dana, an American geologist and mineralogist.


Visual characteristics of Howlite

At source, Howlite is usually found in irregular shaped nodules that look a bit like the head of a cauliflower. Howlite in crystal form (as shown in the above picture) is rare.

Howlite has a white marble-like appearance with threaded gray, black or brown veins running through it. Some forms of Howlite are just pure white however. Howlite is a porous stone that can absorb dye well, which is why it’s often used to imitate other gems.

Some dishonest gem traders will try to pass Howlite gemstones off as more expensive semi-precious gems (like Turquoise, Coral and Lapis Lazuli) after it’s been dyed, but there are some ways to tell the difference.

Usually, these “fake” gems will look a little too perfect because genuine gemstones tend to have natural color variations. You can also tell sometimes in the description or labelling of a product whether or not it’s a substitute for the real thing.

In our opinion, Howlite gemstones should be appreciated for what they are, rather than what some people would prefer them to be – after all, they are very beautiful in their own right!
