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.

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
