Howlite - Sold


Howlite is a calcium borate silicate related to datolite. The type locality is in Nova Scotia. Dana & Brush (1861) in Dana's Fifth System of Mineralogy, named the mineral after Henry How (1828-1879), Canadian chemist, geologist, and mineralogist, University of King's College, Halifax. In California, porcelain like nodules from Tick Canyon are popular lapidary material. Rarely at the famous deposit at Boron, miners found cauliflower like masses such as this. An interesting looking sample!
