Howlite Double Butterfly Pendant from China
Howlite
Howlite is a calcium borosilicate that is usually white with grey to black veins, giving it a marble-like appearance. Because of its porous structure, howlite is often dyed to resemble turquoise. The mineral was discovered in Nova Scotia, Canada, in 1868 and is named after Canadian chemist Henry How.
Howlite occurs mainly in Canada, China and the United States, particularly in California. It forms in boron-rich evaporite environments and is often found in small-scale deposits within sedimentary rocks. Its chemical formula is Ca₂B₅SiO₉(OH)₅ and its hardness is 3.5 to 6.5 on the Mohs scale.

Double-Binder Pendants
The stone cut into double-cylinder is fixed in a silver- or gold-coloured holder with eye. The double-inder has a length of about 3.2 cm, measured without the eye. These pendants are available in various stone types and are supplied individually. Due to the use of natural stone, colour, markings and finish may vary slightly from one pendant to another.
