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.
I was skeptical about Gemselect at first, seriously, but decided to undergo an exploratory transaction and purchased a white sapphire. I expected to be disappointed, but was floored when the package arrived within SEVERAL days of the purchase. I even sent an email to Gemselect and they respond immediately (different time zone ofcourse). VERY VERY SATISFIED, and yes, this review is genuine.
