About howlite
Howlite is a calcium borosilicate hydroxide that typically appears white to gray with characteristic gray or black veining in a marble-like pattern. It is porous, opaque and relatively soft, with Mohs hardness around 3.5. In gem markets it is widely used both in natural form and as a porous substrate for dyes, often imitating more expensive stones such as turquoise or lapis lazuli.
