Howlite
aka White Jasper, White Turquoise, Albino Turquoise
This calcium silicoborate is naturally white, often with a
dark gray or black spider-web matrix. Because it is so
soft and porous it is easily dyed into rich hues to imitate
pricier gemstones. Howlite is commonly dyed to imitate
turquoise and lapis lazuli. This stone should be kept away
from acids, solvents, rough handling and prolonged exposure
to strong light.
Howlite is named after mineralogist
Henry How, who first discovered the gemstone in Nova Scotia
during the 19th century. North America is the
world's primary source of howlite. |
