Tiger eye or tigers eye is a member of the quartz family of stones. It is a brownish-gold gemstone to a reddish gold gemstone that may produce a chatoyancy or flash when it is turned in the light.  This flash is said to resemble the "eye's of a tiger" and thus that is where the name comes from. It also will come in purely red and blue colors, although more rarely. Sometimes the gold brown variation is called hawks eye.
