Blue Howlite Medium Tumblestone 20-30mm, China 250g) NETT

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. With natural turquoise becoming a rare mineral, dyed Howlite is an affordable substitute.
