Howlite is a silicate mineral found in evaporate deposits and was discovered at Tick Canyon California in 1868. In appearance it is white with fine grey or black veins in an erratic often web-like pattern and is opaque with a sub-vitreous lustre. Because of its porous texture howlite can be easily dyed to imitate other minerals especially turquoise because of the superficial similarity of the veining patterns. The dyed howlite (or magnesite) is marketed as turquenite. We always aim to describe our products accurately and as such this particular product is dyed Howlite.
