Large White howlite tumble stone

Howlite is a mineral from the group of silicates, belonging to the group of rare minerals. It owes its name to the nineteenth-century chemist and mineralogist Henry Howa, because he was the first to discover and describe it in Nova Scotia, Canada.
As with all white stones, the howlite is believed to bring peace and clarity to the mind - however, its black lines mean that the mind is still working, that it is focused, not cut off. Howlite is primarily a calming stone. It can help you fall asleep or calm an overactive mind and help you relax.
