Howlite is named after mineralogist Henry How, who first discovered the gemstone in Nova Scotia during the 19th century.
North America is the primary source of howlite, California and Nova Scotia being the primary locations it is mined. This calcium silicaborate is naturally white, often with dark gray or black spider web matrix.
Howlite is known as the stone of memory, knowledge and progress. It is purported to encourage reasoning, observation, discernment, patience, and tact.
