Tiger Eye, a form of quartz, would have a white streak, as would all forms of quartz.
Amethyst, being quartz, would have a white streak.
The streak color of sandstone is typically white or colorless, due to its composition of quartz grains. This can be tested by rubbing the sandstone on a streak plate to observe the color left behind.
