Azurevein? (Vein -geology or botanic means)
The above damascus picture remembers me the
azurita crystal (I don't know how to say it in english but i think it's also known as blue copper ore
EDIT: it's Lapis Lazuli or azurite in english)
Azurita It's a copper derivated (I think the correct traslation is copper's hydrated carbonate) It's dark blue colored.
Facts: Hindus ensures that azurita helps to burn the karma (bad actions in life). In tradition, it's a symbol of power and royalty. Egyptians used this as a cure for poisons and heal some illness.
Hindus uses azurita in the third eye to free the mind. It raises the spiritual level, makes the body more sensitive, provides vitality and unblock the chakras.
A persian leyend thoughts that earth was laying over a huge azurita crystal and its reflects gaves the color to the sky.
