Howlite is a naturally white sedimentary stone, but it is often dyed bright colors as a substitution for more expensive or rare stones. Turquoise Howlite is the most common example of this. White Howlite can coordinate with both silver and gold metals. This stone also looks striking and eye-catching in jewelry designs with black gemstones like Onyx and Black Tourmaline. 

Howlite was first discovered in Nova Scotia in 1868 by Henry How, a famous Canadian mineralogist for whom the stone was named. Howlite is currently found in parts of the United States and Canada. Most Howlite today is sourced from Southern California.

In the metaphysical gemstone community, Howlite is known as the Harmonizer stone. It is thought to contain healing properties that can be used toward conflict resolution and positive collaboration in the workplace.
