Howlite White is a beautiful milky white stone that looks like marble but it is harder and more porous than marble.
These are beautiful natural white stones that have not been tumbled or polished. Some stones contain gentle grey markings.
Howlite was named after Henry How, who discovered it in 1868 in Nova Scotia. Henry 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 that forms as irregular nodules which can appear in the shape of a cauliflower head. Howlite has the appearance of white marble or porcelain with a sub-vitreous luster. Transparent howlite crystals are extremely rare.
Howlite, a calcium borosilicate hydroxide (Ca2B5SiO9(OH)5), is a borate mineral found in evaporite deposits
