Howlite
By chemical composition, howlite is a calcium borosilicate hydroxide. It was first discovered at Tick Canyon in Southern California in 1868. It was named after Henry How (1828-1879), a Canadian mineralogist who first described it.

Howlite is typically white or grayish white with fine grey or black or brown veins, often in a web-like pattern. It is opaque with a sub-vitreous luster sometimes described as porcelaneous. It is usually found in borax deposits in the desert clays of California.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
