Ruby
Ruby - Is a type of corundum that ranges from pink, crimson red and orange-red. It can be translucent, as the rarest rubies are, to opaque. Star Rubies display asterism, a six pointed star-like luminosity caused by a small inclusion of small cylindrical cavities within the stone that are parallel to the prism planes. Asterism is considered to be protective, and ruby is said to be a protective stone, even without a star. It is supposed to stabilize economic status; as long as the water has a bit of ruby, wealth will never depart.
